Another iteration, another comparison.
I've shown the white (Adam) and the orange (JE) variant before, the red one in the middle is new.
I've reverted the change at the front, changed the colour from yellow to red because of the printed bricks I found (or didn't find, as in "anything yellow")
I've added one stud to the wheelbase, now it's just between the othe two, and looks even more like the prototype. I can tell why Adam had it shorter: his roof consists neatly of two 6x6 tiles, but as I have only one of these I don't care much.

Menger sponge
From Wikipedia, the free encyclopedia
An illustration of M4, the sponge after four iterations of the construction process
In mathematics, the Menger sponge (also known as the Menger cube, Menger universal curve, Sierpinski cube, or Sierpinski sponge)[1][2][3] is a fractal curve. It is a three-dimensional generalization of the one-dimensional Cantor set and two-dimensional Sierpinski carpet. It was first described by Karl Menger in 1926, in his studies of the concept of topological dimension.[4][5]
Construction
The construction of a Menger sponge can be described as follows:
Begin with a cube.
Divide every face of the cube into nine squares, like a Rubik's Cube. This sub-divides the cube into 27 smaller cubes.
Remove the smaller cube in the middle of each face, and remove the smaller cube in the center of the more giant cube, leaving 20 smaller cubes. This is a level-1 Menger sponge (resembling a void cube).
Repeat steps two and three for each of the remaining smaller cubes, and continue to iterate ad infinitum.
The second iteration gives a level-2 sponge, the third iteration gives a level-3 sponge, and so on. The Menger sponge itself is the limit of this process after an infinite number of iterations.

Properties
Hexagonal cross-section of a level-4 Menger sponge. (Part of a series of cuts perpendicular to the space diagonal.)
The n nth stage of the Menger sponge, M n M_{n}, is made up of 20 n {\displaystyle 20^{n}} smaller cubes, each with a side length of (1/3)n. The total volume of M n M_{n} is thus ( 20 27 ) n {\textstyle \left({\frac {20}{27}}\right)^{n}}. The total surface area of M n M_{n} is given by the expression 2 ( 20 / 9 ) n + 4 ( 8 / 9 ) n {\displaystyle 2(20/9)^{n}+4(8/9)^{n}}.[6][7] Therefore, the construction's volume approaches zero while its surface area increases without bound. Yet any chosen surface in the construction will be thoroughly punctured as the construction continues so that the limit is neither a solid nor a surface; it has a topological dimension of 1 and is accordingly identified as a curve.
Each face of the construction becomes a Sierpinski carpet, and the intersection of the sponge with any diagonal of the cube or any midline of the faces is a Cantor set. The cross-section of the sponge through its centroid and perpendicular to a space diagonal is a regular hexagon punctured with hexagrams arranged in six-fold symmetry.[8] The number of these hexagrams, in descending size, is given by a n = 9 a n − 1 − 12 a n − 2 {\displaystyle a_{n}=9a_{n-1}-12a_{n-2}}, with a 0 = 1 , a 1 = 6 {\displaystyle a_{0}=1,\ a_{1}=6}.[9]
The sponge's Hausdorff dimension is log 20/log 3 ≅ 2.727. The Lebesgue covering dimension of the Menger sponge is one, the same as any curve. Menger showed, in the 1926 construction, that the sponge is a universal curve, in that every curve is homeomorphic to a subset of the Menger sponge, where a curve means any compact metric space of Lebesgue covering dimension one; this includes trees and graphs with an arbitrary countable number of edges, vertices and closed loops, connected in arbitrary ways. Similarly, the Sierpinski carpet is a universal curve for all curves that can be drawn on the two-dimensional plane. The Menger sponge constructed in three dimensions extends this idea to graphs that are not planar and might be embedded in any number of dimensions.
The Menger sponge is a closed set; since it is also bounded, the Heine–Borel theorem implies that it is compact. It has Lebesgue measure 0. Because it contains continuous paths, it is an uncountable set.
Experiments also showed that cubes with a Menger sponge structure could dissipate shocks five times better for the same material than cubes without any pores.[10]
Third iteration of this ship. Latest changes based on feedback I've received. A little less rough edges. Testing Wicked Brick stand for the first time.
I'm excited to be part of the next iteration of the New Hashima City cyberpunk collab, coming to Brickworld Chicago 2023. I started with train cars, then a cube, and things always escalate with me, so now I've built two of them. Like the first, this one belongs in the docks (aka sector 6, hence the giant 06 on the side), and the large strut on the front (similar but not quite identical to the strut on my first) will support one of the landing pads on Alec Doede's cube above. I envision this as a slightly seedy seller of robot parts of questionable origin. As an Easter Egg, though, the display in the window features the classic M:Tron and Blacktron droids, as these were probably the two most influential Lego space themes of my childhood. I spent a lot of time going crazy on the details on this one, since with time constraints being what they are I probably won't finish a third. In particular I put an inordinate amount of effort into upping my decomposing concrete game, especially on the right side (not shown in the main photo).

Iteration on the Sharpless catalogue of faint nebulae.
It's not a common object, and here is the close up. Very faint and difficult. I am really proud of it :D
Sh2-170 is an emission nebula in Cassiopeia at around 7500 light years away.
The bright star at the centre of the nebula is ionising the surrounding hydrogen gas, causing the nebula to glow.
This nebula is about 2/3 the diameter of the full moon.

Red Sands anti-aircraft battery, with Shivering Sands battery in the distance.
Designed by Guy Maunsell and built during the Second World War, these batteries were intended to deter enemy bombers from using the river Thames to navigate their way into Central London.
Have taken out one of the two seams I'd done with "iteration one" of the double-herringbone pattern, and redone it using wider stitches somewhat more closely spaced, but touching. When under normal wear tension, this stitch looks much more like that on the seams of the original piece.
Hector the Convector is a cumulonimbus thundercloud that forms regularly nearly every afternoon on the Tiwi Islands (90 km NNW of Darwin) in the Northern Territory of Australia, from approximately September to March each year. Hector is known as one of the world's most consistently large thunderstorms, reaching heights of approximately 20 kilometres (66,000 ft).
Named by US and Australian airforce pilots during the Second World War, (who were attempting to defend Darwin against Japanese bombing) the recurring position of the thunderstorm made it a navigational beacon for pilots and mariners in the region. Hector is caused primarily by a collision of several sea breeze boundaries across the Tiwi Islands and is known for its consistency and intensity. Lightning rates and updraft speeds are notable aspects of this thunderstorm and during the 1990s National Geographic magazine published a comprehensive study of the storm with pictures of damaged trees and details of updraft speeds and references to tornadic events.
Since the late-1980s the thunderstorm has been the subject of many meteorological studies, many centred on Hector itself, but also utilising the consistency of the storm cell to study other aspects of thunderstorms and lightning.

Second iteration already, this time using all SBIG data. I did collect some really bad color data the same night I collected the luminance data, but wanted to try the DSLR color first (previous iteration). This one turned out much nicer.

New iteration of an image taken two years ago. A white veil on Lake Dupuis, a mixture of snow and tears, an animal has passed by, snow up to the ankles, a path to clear, towards the planet closest to this opaline universe... K70 +50mm f/1.8
Here is the fourth iteration of this shot which I've done on every 365 so far.
The background is a camera rotation shot I did at Media City ages ago, committed to print on a canvas.
This year was a bit harder due to my camera screen being broken. I've been displaying live view on my phone screen via the app but I needed my phone to display the shot from last time.
Guessed my hand position and fired off a few shots. Lit from above with a flashgun with orange gel through the beauty dish. Second unit on the floor through a snoot to control the spill of light.
Fog forecast for tomorrow afternoon in the hills so that's where you'll find me.
Happy days.

Sure, everyone does it and I've seen better iterations in better light, but this is one of those places I've always dreamed of seeing coffee myself. Sadly the parking lot here on Skyline Drive seems to be a popular hangout for the seedier elements of Duluth and hence it was covered with an utterly disgusting amount of trash and litter all in the woods along the hillside which definitely detracted from the experience.
Regardless, the view did not disappoint with the sweeping vista of St. Louis Bay and massive port infrastructure lining both sides. The morning Proctor crew has a trio of tunnel motors led by fan favorite SD40-3 BLE 909 (originally built as an SD45T-2 in Feb. 1973 as SSW 9277) strung out on Dock 6 as they finish unloading pellets. This dock was built by the Duluth, Missabe and Northern in 1917 while the snaking trackless trestle at right leads to Dock 5 which dates from two years prior. Alas the mile long s-curve trestle approach and the dock itself felt the weight of their last train in 1985 and remain as an abandoned monument to the shrinkage of of the once mighty domestic steel industry. To see some fabulous photos from years past and to learn more about the docks I found this post super interesting:
towns-and-nature.blogspot.com/2022/05/duluth-mn-cndm-5-an...
The track leading downhill and curving of to the left is the mainline that takes the Run Down trestle to Missabe Junction and water level where limestone trains access the docks via BNSF's ex NP waterfront trackage. In the background is the Midwest Energy coal terminal served by BNSF and occasionally Union Pacific (sharp eyes will note a UP train at the dumper) and beyond that the 12 million bushel capacity General Mills elevators S and X. To learn about the coal terminal and the changing market check out this: www.minnpost.com/environment/2020/04/as-energy-use-change...
And to learn about the various elevators and capacities in the twin ports this is a cool link: www.bluetoad.com/publication/?i=28295&article_id=2827...
This is a railroad that should need no introduction to even the most casual fan as the Duluth, Missabe and Iron Range Railway is in a word legendary. I won't bore you with pages of history as I couldn't do the road or region justice anyway. It simply needs to be experienced for oneself. But I will direct you to two resources. Absolutely check out the fabulous historical information here: www.missabe.com/

I've posted other iterations of this bench, which sits beside a trail in the Corte Madera Marsh, but this one I did especially for Sliders Sunday. All the sliding was done using a few Topaz presets, all of which were individually tweaked to get this result. This bench is one of those things I just can't pass by without taking another shot or two or three of it, in hopes that maybe I can come up with something different from all the previous shots I've taken. So far, this is my favorite, but I'd be willing to bet this isn't my last attempt.
A Flickr Friday submission on the subject "Tee". In this selfie, I am wearing a tee-shirt, carrying a picture of me wearing a tee shirt, on which there is a picture...
This is a long-term project which has already gone through several iterations,
Just the first iteration on a classic british car from the sixties. This is very much work in progress, not with the parts I'd like to have, but with those I had in my stash - and you know how it is. Regardless hove many bricks you have, you never have the right parts!
Not telling you what it's going to be, because I am curious if it's recognisable just from the shape.
My iteration of what Bucky Barnes would like like as a Captain America.
Also comment whether you guys like the new showcase style I'm doing for some of my custom minifigs!
This loco has evolved through several iterations from an Emerald Night. At this point I don’t think there is any significant part of the Emerald Design left!
My first version was powered by an XL using the original Emerald Night gear train. Finding this a bit slow, for the second iteration I tried two L motors, one mounted in the firebox and the other inside the boiler. This was a bit better, but still not that fast when pulling carriages. This version has two train motors, one under each tender and can pull four or five cars at a good speed. There are two battery packs, one in each tender, for extra battery life and weight.
I had to make the tenders slightly longer to fit the motors. Also of note, to avoid too much play between the tender and loco, the rear wheels of the loco are the leader tender wheels are joined are rigidly attached.
Historically speaking, at least the third iteration of signaling has recently sprouted at Bridgeport Junction, the northernmost / westernmost end of CN's ex-IC Chicago Sub, where it splits into the former Iowa Division (the Freeport Sub) and the ex-GM&O main line (the Joliet Sub). One of the formerly-signaled tracks in Bridgeport "Yard" (once one of the main IC Iowa Division tracks) has finally been removed, leaving just one long runner track, and further east, a short passing siding for runaround moves, which this local has just utilized. CN 9566 and a fellow ex-IC unit, plus a GTW geep, move through the junction alongside CTA's Orange Line, and head for Hawthorne Yard on the Freeport Sub, on a surprisingly cool summer evening.
Iteration 3.1, responds to certain concerns brought up in the iteration 3 blog post.

This plasmapheresis machine extracts blood, filters (red round tube, top right) and guides the plasma into a plastic bag (light yellow, not seen in this frame) and the rest of the blood flows into that transparent reservoir with the sticker on it. When the reservoir is full, it is loaded back into your vein. It takes about 10 or 11 iterations and 50 minutes before 800ml of plasma is extracted.
When donating plasma, you don't feel weak afterwards, you don't feel any different. When donating blood you do feel a bit weaker and it takes some time to recover. Therefore I prefer plasma donation.
My last donation was in 2013 and I'm back now. This was donation number 54. My dad used to be a donor and therefore I'm one now. This Rotterdam branch has been renovated in the meantime and they have a lot more space and capacity now. All new furniture, glass all around and the machines look more advanced.
While donating, they offer something to eat and drink and you can read a magazine or newspaper. The staff is super friendly. It is very relaxing. It is just an hour doing nothing. Quality nothing time.
