This is a work in progress. This is not a raytraced image. Raytraced images are drawn one pixel at time, which is a relatively slow process. Since all the objects in the image are bounded by flat surfaces, and the number of surfaces is much smaller than the number of pixels in the image, it is much faster to construct the image by drawing fewer, larger polygons, rather than the more numerous pixels one at a time.
Some faceted objects are easier to draw than others.
In other worlds, if you wrote a little program to draw convex objects quickly, and then forced it draw some thing more complicated, well you might get an image renderedly improperly, like the image above. The neat thing about this though, is the program spins the web of conecting strings on the fly. Two views of our friend the Dodecahedron. The Dodecahedron has 12 sides, and for each side, there is an opposite face, parallel to the first. With a little bit of imagination, this is like staring down the barrels of a double barrelled shot gun.
