JS port of Kensler's famous 1337-byte C++ business-card ray-tracer. My initials "glebv" is spelled out in reflective mirror spheres over a checkered floor. Full Monte-Carlo: 64 samples/px, depth-of-field blur, soft shadows, Phong specular, sky gradient. Hand-golfed to ~1.1 KB then crushed even further with jscrush.
