8192 triangles are drawn in 3 dimensional space and used to approximate a source image. An algorithm refines the colors and positions of the vertices until the image converges on the target.

When processing any black&white photos from film negatives I usually pull the "Contrast" slider all the way to +100 as a default starting point. This is also part of my standard b&w film Lightroom preset (which otherwise includes some of the steps shown in this guide - I really recommend creating presets if you often make similar adjustments to photographs!). Of course this contrast increase is only a matter of taste - I like my contrast high in most of my pictures, while I know others prefer a softer grayscale. When you have your negatives digitalized in RAW format you can really do a lot of adjustments. I prefer to stay quite close to the original feel of the film, otherwise I wouldn't have taken the detour via the analog technique instead of simply shooting digital. :)
For this particular example, I shot a roll of HP5+ (400 ISO film) at ISO 800 and the film was pushed one stop in development. This in itself added some contrast, so I might not have needed to add as much extra contrast here as I usually do. It might have just sufficed to adjust the white point and black point of the RGB curve (more on that in a later step).
This is a shot of author Pat McManus I shot earlier this spring. I StumbledUpon an online Photoshop CS3 tutorial recreating the Cross-Processing effect. Back in the days of film, chemistry was a big deal. Each individual film stock had precise chemistry and processing recipes that had to be followed to generate the desired look. Occasionally, photographers would have happy mistakes where they followed the wrong recipe for particular emulsion. Colors would shift dramatically, grain would enlarge.
This is my attempt at recreating the effect. I had to tweak the tutorial a little bit . I think it looks like a lot like The Matrix. I recreated a film frame too.

This Demonstration shows orbit of the 2D coupled logistic map. This system exhibits chaotic behavior when Lambda parameters lie in the neighborhood of the region [1.032, 1.0843]. For certain values of the parameters and the initial conditions, the dynamics can also converge to periodic orbits. Using the slider controls you can vary the initial conditions of the orbit and the values of the two parameters of the system.

Playing with the Hemesh and Convex Hull by Lee Byrons library. Starting Point is the Hemesh Voronoi example. The voronoi cells are subdivided and then slices of the vertices are sent to the convex hull algorithm.
They are abviously inspired by jtnimoys awesome work for the tron movie.

Taken in the Ellis Island National Museum of Immigration.
Ellis Island acted as an immigrant inspection station 1892-1934. The main building is the second on the site (the first, a wooden building, lasted 1892-97 before burning down). The replacement structure was designed by Edward Lippincott Tilton and William A. Boring. The Main Building was built 1897–1900, and the Kitchen and Laundry Building, Main Powerhouse, and Main Hospital Building built 1900–1.
