Revisiting the classic twister effect, but this time it's done the 'right way', or so I think at least. :S
So all the 'twisting' are now done in the vertex shader depending on the y-position of the vertex.
Also added a slight 'wobble' this time. Plus some kinda 'rotozoom' effect in the background.
Really fun to play with these kinda things, allthough I'm an utter n00b.
Note. You need a modern browser that supports WebGL for this to run the way it is intended.
For example. Google Chrome 9+ or Firefox 4+.
(If you are already using one of those browsers and it's still not running, it's possible that you
have old blacklisted GPU drivers. Try updating the drivers for your graphic card.
Or try to set a '--ignore-gpu-blacklist' switch for the browser.)
