Triangles by Border of Div - October 2006
Useless Pickles (Jeff Lau) shows polygons drawn by many triangles made by <div> elements using trick of borders. It means we could develop Virtua Fighter (1) by JavaScript.

3D Renderer with Textures - March 2008
Triangle Texture Mapping on Wii - April 2008
Daniel Gump released Wii Opera SDK which had triangle texture-mapping feature. It is a SDK for Nintendo Wii's Internet Channel. He said it could show 500 textured triangles per second on Wii.
Motion Blur - May (maybe) 2008
Kaarel Lumi represented a beautiful motion blur using alpha blending tech by fillStyle. Thanks, @moriyoshi.
Projective Texturing - November 2008
Steven Wittens also wrote projective transform renderer. I'm interested in the tech which make an adjustment on size of the image cutted. It makes many cuts for front pieces.
Sphere Environment Mapping - February 2009
Satoshi Ueyama reported that Chrome had extremely fast canvas rendering engine named Skia by demonstrating his demos and benchmarks. He also described in detail how to implement texture mapping by canvas in his post. He also implemented physical computing and sphere environment mapping feature on it. His demos showed us that now we could run JavaScript 3D by real-time / daily-usable performance on Chrome. And I guess rest of popular browsers will soon come to the stage. See also my post.
