Once again, here is my standard comment every time somebody puts out a Canvas app:
Please add the ONE line of code required for this to run in IE
Look, Internet Explorer had VML support way back in IE5, and it's trivial to emulate Canvas with it. Google even supplies a library that you can include:
... which would explain why it doesn't work in Chrome either.
It's surprising that they would put this out into the world as though it were finished, seeing as it runs on such a small slice of the world's browsers.
Seems like there's nothing there that couldn't work in Canvas (and thus be usable in every major browser). I wonder why they chose such a dead-end tech to do it in.
