Most useful thing I got out of that:<p><a href="http://www.iquilezles.org/apps/shadertoy/" rel="nofollow">http://www.iquilezles.org/apps/shadertoy/</a><p>Kinda fun. Though I'm getting a fair number of errors on the presets, only about 2/3 of them work properly.<p>edit: tried in Webkit + WebGL: nice whale. Is it really 80k triangles? Gotta love the render speed :)<p>Definitely more interesting in a WebGL browser, but could really have used more fun with that cube. It just seems... random. Like there wasn't enough <i>3D™</i> or something.
