Quasi-fractal makes sense to me, I'm assuming that the gears are created from generic fractal-generating code (pass a basic geometric pattern, draw a portion of a self-similar fractal) that's been modified to create finite gears instead. Or I could easily be talking nonsense. The page itself is really cool, and I love the effect. I wonder if I would be able to use screenshots from it for personal projects? I assume not. As the most minor point that could possibly be made – never seen · before, seems like it could be quite useful.
