Via BlenderNation, a script for exporting blender 3d models to javascript. This reminds me of Samuel Johnson's quip: "Sir, a woman's preaching is like a dog's walking on his hind legs. It is not done well; but you are surprised to find it done at all." The conversion is approximate and the animation slow for non-trivial models, but it is impressive to see plain javascript doing this. Kudos to useless pickles for the core triangle-drawing trickery.
