I was happy to find that my site has been getting discovered out there. Today, http://learningwebgl.com/blog/ and 3 other sites have posted my WebGL Tetris link and traffic has increased by 30x more than it’s highest day in the short month that the site has been running. Thanks for checking it out and be sure to come back, I’ll have many more features implemented, and some releases, eventually.
Here’s the link: http://phillihp.com/projects/creating-tetris-with-opengl-and-webgl/. Let me know if your having trouble getting it to run.
