blur the backbuffer

[aNt]

anyone got a routine that can do an all over blur to the GL backbuffers ? would be most cool if anyone had one.

Gaussian blur hack:

read the back buffer (to texture/bitmap/wjatever) and redraw it with different offsets located within a circle. If you draw *n* images then change the colour scale to 1/*n*
