You could try blurring the scene by rendering it in a tiny window and
"rectzoom"ing it up to VGA. You could have multiple fields of focus by drawing
the scene once for each field and slicing them up with near/far planes or 6
axis clipplanes. You would need to layer the slices somehow, that would work if
rectzoom zoomed up the alpha values as well as RGB as each slice would have
transparent sections to see down to the next one. I just made this up so it has
no bearing on real GL but it might work....
Oh yes I have just thought - rather than all that rectzooming - you could
render your slices into texture maps usin fbsubtexload ( or some dodgey openGL
equivalent! ). Then I know you will maintain the alpha. My that would be a fibe
demo if it worked.

I wonder if Sirius video could help you, then you can render on one pipe and
pur the pixels into a texture map on another. That would improve your
performance but increase your latency.
