I was driving by the former site of the Rockwell Gardens housing project, and I decided to take a few more shots. None of them really convey the awesome emptiness of that lot, but I found of them interesting for other reasons.
This shot is of the treads on this beast. It's probably best viewed large.

I stumbled on this gallery as I was photographing the Nan Lian Gardens. All the signage was in Chinese and there is a dearth of information on the net but the gallery’s purpose is visually apparent. The Chinese Timber Architecture Gallery shows, in miniature, how many of the buildings in both the garden and the adjacent nunnery were constructed. The elaborate chocks, blocks and joins that hold the roof together, without the benefit of nails, is put on display. The designs are both elaborate and attractive. Impressed!
Five Interlocking Truncated Tetrahedra #2 90 units 5-fold view.
A new wireframe design, one that I have known was possible for a long time. This solidifies the 20 Triangles compound into a sturdy, decent compound. It has a very Daniel Kwan-esque look to it, which is probably appropriate given that he designed the first 5 Truncated Tetrahedra compound. A cp is up for it, if anyone cares.
Designed by me.
Folded out of Astrobrights copy paper.
Where does a "Big Fig" hang out nowadays, were he knows he won't be out of place among your legions of minifigures.
Our "Big Fig" bases, that's where! With the amount of custom "Hulk" size custom figures, showing up, we created a line of detailed display bases to showcase them properly, in all their "Big Fig" glory. These unique bases are cast in resin plastic, hand painted, then sealed for protection.
All of these bases are compatible with all "Big Fig" size large & small minifigures. They also interlock with similar bases designed by us to create a custom Display piece. All vertical back pieces are removable/interchangeable with other bases to further your choice of creative display combinations.
Other breakthrough designs are already in the works, for release in the next few months, as well as a hanging bracket, specially designed to wall mount your custom combination display of up to 8 bases wide!.
Pricing to be announced in the next few weeks.
Please FM us for all inquiries at the present time.
The metal panelled fence that tops the sea wall near Tollesbury is a great photographic subject! I love the way the metal panels are 'locked' together!
Five Interlocking Truncated Tetrahedra #2 (Byriah Loper) - 5-fold axis
Once again, this model could've taken me a lot less time to make, but school got in the way (again). It was a bit tedious to make all 90 units, and a bit of frustration assembling. I used a mix of bottom-up and frame-by-frame for this one. Suprisingly, though, it's rather loose. Oh well... Other than that, an awesome model by Byriah Loper!

PS: I think I'm only the second person to recreate this :-D
Back in the early eighties, eastbound freight from Streator, Illinois crosses the former Nickel Plate. This is Osborn Tower, that was located in Hammond, Indiana's Hessville section.
Insensible à la modernisation inévitable des signaux sur les voies aux alentours, le vénérable signal à lentilles gouvernant les trains en direction est sur la traversée de voie à De Beaujeu se tient toujours debout - pour l'instant du moins. Ni VIA Rail, ni le CP ne semblent désireux de modifier les paramètres du module de signalisation automatique à cet endroit, ce qui devrait nous permettre de l'observer pendant encore quelques années. / As searchlights signals on nearby trackside locations inevitably fall to a wave of modernization, this old searchlight signal governing eastbound movements across the diamond at De Beaujeu is not going anywhere, for now at least. Neither VIA Rail nor CP seem in a hurry to modify the parameters of the automatic signal box for this diamond, which should make it safe for a few years.
in the first snow.
I'm not sure, if someone has made it before. It looks very simple. And I'm also not sure, if this is only a subfigure of a bigger stucture.
It has a 3-fold-axis and three 2-fold-axes. Here is the model along the different symmetries.
folder: Dirk Eisner
designer of the unit: Tomoko Fuse, Francis Ow, Dirk Eisner
36 units
last unit: 05.12.2012
paper: metallized kraft paper
paper size: with the method by Tomoko Fuse 1 : 1.5
I used an extra amount of paper at each end, that is only 3/4 of the width of the frame, to get nicer vertices. So I used 1 : 1.375 .
Folded from six uncut A4 sheets featuring the printed wood plank pattern I normally use for building origami framework structures.
My design was inspired by the model Rohre by Alessandro Beber. It uses a non-Sonobe, non-chiral basic unit with some potential for further modification. Here are the instructions.
As far as I know these were the first interlocking building bricks made from plastic. They were designed by Hilary Page as a safe and hygienic alternative to painted or polished wooden bricks.
They are a technological ancestor to the Kiddicraft Self Locking Building Brlcks and the LEGO bricks.
These bricks were introduced in 1939. Hilary Page applied for a patent in 1939 (patent application No 11577, now known as GB19390011577) which was awarded in 1940 and became patent No 529580 (GB529580). Before the second World War, these bricks were sold under the brand name "Bri-Plax" (British Plastic Toys Ltd). During the war production ceased, but in 1945 production was resumed and the bricks were sold under the brand name "Kiddicraft".
Questions
- Does anyone know until which year these Interlocking Building Cubes were made & sold?
- Does anyone know if these bricks can be dated by the mold version (see the different texts inside) or their color?
- How many versions of these bricks exist? Are there more mold versions? I've read different sizes exist and there might be more versions than the two shown in my photo...

P.S. I'll return to adding LEGO 2x4 bricks soon ;-)
The eastern end of the Bloomingdale Branch began here at Clyborn Junction. The Metra tracks and station are just behind the Kennedy Expressway viaduct.
Remainings of an interlocking tower on the territory of the former Berlin Tempelhof classification yard, which was closed in 1952.
Mechanical interlocking machines were used to control the signals and switches at certain junctions where control was best handled by an operator on the ground. The machine was house in a building called a tower. Each lever controlled a switch, signal blade or lock. The levers were locked together so that a certain order must be followed (i.e. switches must be thrown before the signal can be set to clear). They are also locked to prevent conflicting routes from being set up. For example, if the signal facing eastbound traffic shows "clear", the signal in the opposing direction is physically locked so that it can't display clear until the opposing signal is returned to "stop" . This type of machine was connected to the signals and switches by a mess of cables and linking rods run next to the track. The last installation of this type in the United States was at Brighton Park, it closed in 2007. The link has good photos of the signals and linking rods. This video show the same sort of machine in operation in the UK, where this technology originates.
My machine does not use the same methods to lock the levers as the actual machines. However, I was able to mimic the same functions using sliding bars and thread. This machine is my prototype and will have ten levers when I have the parts. All levers are interlocked to each other completely, making it is impossible to give conflicting routes.
Ultimately I'm not building one machine but rather, I'm building principles I can use to make mechanical interlockings for any track diagram. Once I have the prototype machine connected to the appliances and debugged I'll be ready to start a more complicated installation.
WX tower in Warwick was pretty quiet on a recent Friday afternoon. The tower no longer controls switches and signals and is used by the CSX maintenance of way forces.
Five Interlocking Truncated Tetrahedra #2, designed by Byriah Loper, folded by me.
Another wireframe, finally! By far the most fun wireframe in a while. This one is not too hard, but pretty nice and challenging too. Not the ones you would pull your hair on, because of stress. :P
I finally got to actually fold this after a while, because, you know...illustrating stuff.
Enjoy!

My first upload of 2012 which was taken yesterday morning when there was a slight covering of frost, which can be seen in the foreground. I've visited here a few times but never been able to come away happy but I find the colours really nice in this shot. The sun was just rising so the foreground grasses have a little glow about them as does the hawthorn bush.
The northbound track geometry train had the OTHER set of CSX F units on the point! Both sets of Fs by Haley within an hour of each other ... they would have met at Pimento or maybe Sullivan!
The mind, it boggles.
And that's Clee looking out of the tower window. He didn't manage to stay away from the tower for very long! :)
The rear DPU's of the C-CDMMON0-04A train cross the interlocker at Dobbin, Texas. This train is running southbound on the BNSF Houston Subdivision, and is crossing the BNSF Conroe Subdivision.
This is the former site of Tower 70, where the crossing of the Trinity & Brazos Valley Railroad and the Gulf, Colorado & Santa Fe Railway was. History of these two lines is as follows.
The Central & Montgomery (C&M) Railway was chartered in late 1877 by Montgomery interests to build a 25-mile rail line from Montgomery to Navasota, where a connection to the Houston & Texas Central Railway could be made. The line between Montgomery and Navasota was completed in 1878, and in 1882, it was sold to the Gulf, Colorado and Santa Fe (GC&SF) Railway which wanted to build a line east from its main line at Somerville to the lumber mills of East Texas. The C&M line fit well with Santa Fe's projected route, and, despite some legal issues related to the sale, the C&M tracks were extended west from Navasota to GC&SF's main line at Somerville in 1883 and east to Conroe in 1885. The line remains in operation today by GC&SF's eventual successor, Burlington Northern Santa Fe (BNSF) and is called the Conroe Subdivision.
The Trinity & Brazos Valley (T&BV) Railroad was chartered in 1902 for construction of a line between Hillsboro and Mexia, but by 1905, it had become acquired by the Colorado & Southern Railroad under the control of B. F. Yoakum. Yoakum was also the CEO of both the Rock Island and the St. Louis San Francisco ("Frisco") railroads, and he used the T&BV charter to build from Mexia to Teague, and from Teague south to Houston and north to Waxahachie, where trackage rights to Dallas were obtained from the Katy on their Hillsboro line. This created a direct route between Dallas and Houston via Teague for the benefit of Yoakum's other railroads, including the Gulf Coast Lines. The north/south T&BV crossed the east/west Santa Fe line at a small community known as Bobbin. The name was changed to Dobbin in 1909, perhaps to avoid confusion with Bobville, a small town on the Santa Fe line about a mile from the crossing. The T&BV line was unprofitable, causing the railroad to enter receivership in 1914. Receivership ended in 1930 under the newly organized Burlington-Rock Island (B-RI) Railroad; its successor, BNSF, operates the line today as the Houston Subdivision.
Ironically, as of October 2018, this photo is no longer accessible as the road crossing no longer exists, and the road to get to the interlocker is on private property, thus no longer accessible unless you are a railroad employee.
