Damn, that sounds nice...

Ah well. I just get a JavaScript alert telling me that it can't 
initialise shader1, then a couple that say "null", and then a message 
that it can't initialise shader2.

Ironically, I have a nearly identical setup: Opera (so, the Chrome 
rendering engine), Windows 7, and an nVidia 600-series GPU.

Ah yes - it's not like you can just run the Mersenne Twister on a GPU... ;-)
