Warning: This is incredibly epic, and worked fine for me. May cause heart attack due to awesomeness.

No problems for me at all. Chrome 14, Windows 7, nVidia graphics.

Chrome 13, Windows 7 - display driver (Intel Integrated) crashed but Windows managed to recover it. Intel graphics related issue maybe?

That's fantastic. I've been meaning to get into WebGL (perhaps make some sort of tech demo game with it). I've held off because of performance issues (also, I admit, I'm not too excited about dealing with shaders).

I think I should stop procrastinating now and actually do something with it. This is very exciting!

Seems like a general WebGL issue -- I've seen most WebGL examples hang up or freeze on integrated graphics / Intel graphics but they always run absolutely smoothly on "full-blown" gamer-like GPUs (nVidia etc.) Unless your nVidia is on a MacBook but running Linux instead of OSX und thus odd drivers.

Shaders are fun! Looks a bit like "scary c++" at first but not too steep a learning-curve actually. No header files, pointers and the likes. Just a couple of maths functions and maths types (vec3, float etc). Pixel shaders return a "color" vector, vertex shaders a vertex "position" and "that's about it".

Exact same setup and experience for me.

Beautiful... the fading grain as it renders is extremely pleasing.
