It's strange to me that a photo I spend zero attention to taking can become so popular. Lou hates my red phone, the ring is too loud...it's always so alarming when it rings. I'm sure my neighbors hate me.
30"X30" Trinity captures a spark of LIfe at the bottom of an epeiric sea, on an extra solar water world, ~3.6 billion years ago.

I coil alot of cable in my line of work, but this has to be the most beautiful knot i've ever seen form naturally. Or perhaps i'm just paying more attention because of my recursion group!
Another fold of Shuzo Fujimoto’s Hydrangea. I’ve kept two outermost layers free of unnecessary creases. For deeper layers, it becomes much harder.

This is the spiral staircase at The Nethercutt Collection Museum, in Sylmar, CA (Los Angeles area). The museum is open to the public and is free. The section of the museum where this photo was taken is across the street from the "main" museum. It's only open twice a day for guided tours, but is well worth seeing.
Not that I expect you to sit there listening for 28 minutes, but for your musical enjoyment, I recommend Keith Jarrett's The Köln Concert: Part I. In case your time is limited :) my favorite part starts 7 minutes in.

Believe it or not, over all these years of folding tessellations, I never folded a clean tiling of Fujimoto’s Hydrangea. I recently decided to make up for this omission, so here goes the classic.
As with most other similar designs, different molecule packing densities are possible (the one used here is called the dense packing). The edges (“leaves”) can also be finished in multiple ways depending on how many grid units of margin are left around the molecules proper. I plan to post examples of different edge finishes when time allows.

Taming Light #33
With best wishes to you all for a wonderful Christmas and a very happy New Year.
A complex 'recursive' refraction pattern this time. The light beam is first passed through one of my plastic creations and then through one of my textured glass pieces, giving this 'aurora' of light.
For new viewers: These are light refraction patterns or 'caustics' formed by a white light beam passing through shaped and textured transparent forms. The pattern is captured directly on to 35mm film by removing the camera lens and putting the transparent object(s) in its place. Colours are introduced by placing complex coloured optical filters directly in the light beam.
The processed film is digitally scanned for uploading. Please note these are not computer generated images but a true analogue of the way light is refracted by the objects I create.

The Droste effect, known in art as an example of mise en abyme, is the effect of a picture recursively appearing within itself, in a place where a similar picture would realistically be expected to appear, producing a loop which theoretically could go on forever, but realistically only goes on as far as the image's quality allows.
The effect is named for a Dutch brand of cocoa, with an image designed by Jan Musset in 1904. It has since been used in the packaging of a variety of products. The effect was anticipated in medieval works of art such as Giotto's Stefaneschi Triptych of 1320.
The effect is named after the image on the tins and boxes of Droste cocoa powder, one of the main Dutch brands, which displayed a nurse carrying a serving tray with a cup of hot chocolate and a box with the same image, designed by Jan Misset. This image, introduced in 1904, and maintained for decades with slight variations from 1912 by artists including Adolphe Mouron, became a household notion. Reportedly, poet and columnist Nico Scheepmaker introduced wider usage of the term in the late 1970s.
Mathematics
The appearance is recursive: the smaller version contains an even smaller version of the picture, and so on. Only in theory could this go on forever, as fractals do; practically, it continues only as long as the resolution of the picture allows, which is relatively short, since each iteration geometrically reduces the picture's size.
Medieval art
The Droste effect was anticipated by Giotto in 1320, in his Stefaneschi Triptych. The polyptych altarpiece portrays in its center panel Cardinal Giacomo Gaetani Stefaneschi offering the triptych itself to St. Peter. There are also several examples from medieval times of books featuring images containing the book itself or window panels in churches depicting miniature copies of the window panel itself.
M. C. Escher
The Dutch artist M. C. Escher made use of the Droste effect in his 1956 lithograph Print Gallery, which depicts a gallery containing a print which depicts the gallery, each time both reduced and rotated, but with a void at the centre of the image. The work has attracted the attention of mathematicians including Bart de Smit and Hendrik Lenstra. They devised a method of filling in the artwork's central void in an additional application of the Droste effect by successively rotating and shrinking an image of the artwork.
Modern usage
The Droste effect was used in the packaging of Land O'Lakes butter, which featured a Native American woman holding a package of butter with a picture of herself. Morton Salt similarly makes use of the effect. The cover of the 1969 vinyl album Ummagumma by Pink Floyd shows the band members sitting in various places, with a picture on the wall showing the same scene, but the order of the band members rotated. The logo of The Laughing Cow cheese spread brand pictures a cow with earrings. On closer inspection, these are seen to be images of the circular cheese spread package, each bearing the image of the laughing cow.[5] The Droste effect is a theme in Russell Hoban's children's novel, The Mouse and His Child, appearing in the form of a label on a can of "Bonzo Dog Food" which depicts itself.
A three-dimensional example of the Droste Effect can be seen in Bourton-on-the-Water, England. A model of Bourton-on-the-Water was built within the village in the 1930s at a 1:9 scale and contains within it a model of itself, which in turn includes a further smaller model, and then an even smaller model within that.

My first explored picture. Yay!
First time I tried something like this. Could be better in many ways and it will be next time:)
Many thanks to the lovely model:P

Bending Light #68
Another 'double refraction' or 'recursive' pattern. The light is first refracted through a piece of shaped and blown clear glass and then this refraction pattern is passed through one of my moulded plastic shapes into which colours have been incorporated.
For new viewers: these are analog images of the refraction patterns of a single beam of light passing through various transparent objects. The image is captured directly on to 35mm film, no camera lens is used ( this is a photogram using film instead of photographic paper). No Photoshop is used only Picasa2 for alignment and cropping. The slide film was lab processed and scanned for uploading.
When viewed large the fine bands of diffraction patterns and also some faint refraction 'rainbows' can be seen.
To me this is another 'galactic' image deep in space, but you may have other ideas.
Shot on very expired APS film and then manipulated to within an inch of its life in GIMP.
Gives a nice painting-like effect without using a preset.
Basic steps:
1. Duplicate
2. Despeckle top layer with adaptive=no recursive=yes
3. equalise top layer and set to around 50% opacity and merge mode=dodge
4. lower layer despeckle adaptive=yes
HSS!
So in the process of doing our grocery order, online, I added salsa. It wasn’t until I hit the order confirmation that I realized it was going to be shipped— for heaven’s sake!! I tried canceling it but their website was obstinately stuck in an unproductive recursive loop.
I figure it took at least three (probably more like six+) people to get it to us: the person who picked it up off the shelf in the warehouse, the person who wrapped it so carefully and boxed it up, the person who applied the label (that could also be the boxer) and the fedex person who put it into the shipping system, the person who put it on the truck in Johnstown, NY and the person who delivered it just now in eastern New England!!
At least I got a photo op out of this comedic error.

Having acquired an original Droste canister a while back this seemed an excellent opportunity to put it to good use!
This is another fold of Scissors Fractal, a recursive model I derived from Shuzo Fujimoto’s Scissors (CFW 87). See my previous post for a more detailed discussion of this technique. In this fold, the direction each level rotates relative to the previous, alternates every other level.

The goal of this round is to create a recursive model, and I'm rather proud of the result.

A fractal is generally "a rough or fragmented geometric shape that can be split into parts, each of which is (at least approximately) a reduced-size copy of the whole," a property called self-similarity. The term was coined by Benoît Mandelbrot in 1975 and was derived from the Latin fractus meaning "broken" or "fractured."
A fractal often has the following features:
- It has a fine structure at arbitrarily small scales.
- It is too irregular to be easily described in traditional Euclidean geometric language.
- It is self-similar (at least approximately or stochastically).
- It has a Hausdorff dimension which is greater than its topological dimension (although this requirement is not met by space-filling curves such as the Hilbert curve).
- It has a simple and recursive definition.
Because they appear similar at all levels of magnification, fractals are often considered to be infinitely complex (in informal terms). Natural objects that approximate fractals to a degree include clouds, mountain ranges, lightning bolts, coastlines, and snow flakes. However, not all self-similar objects are fractals—for example, the real line (a straight Euclidean line) is formally self-similar but fails to have other fractal characteristics.
Approximate fractals are easily found in nature. These objects display self-similar structure over an extended, but finite, scale range. Examples include clouds, snow flakes, crystals, mountain ranges, lightning, river networks, cauliflower or broccoli, and systems of blood vessels and pulmonary vessels. Coastlines may be loosely considered fractal in nature.
Trees and ferns are fractal in nature and can be modeled on a computer by using a recursive algorithm. This recursive nature is obvious in these examples — a branch from a tree or a frond from a fern is a miniature replica of the whole: not identical, but similar in nature.
