I've been very interested in opening up Lisp to do realtime video 
(raster mostly, as opposed to 3D). However, I haven't even had time to 
move from SC to SND/CLM yet, so video is a ways off. One thought I had 
was to use PDP, which started as PureDataPackets, but is now a C 
library, which it should be possible to interface to with Lisp. A native 
Lisp solution would of course be preferrable. I would be surprised if 
there wasn't already a Lisp facility to work with graphics as matrices. 
It shouldn't be a huge jump to move from there to mjpeg.

I emailed Hanspeter with some questions, if he responds I'll ask his 
permission to further post it to the list.
