Creating barrel distortion of video

[semeon.risom at gmail.com]

Hello - 
This may seem like an odd request for the main python google group, but I thought this question might have answers coming from different backgrounds that utilize python.

I'm trying to find a way of rendering an optical distortion on a video I will be presenting through the use of a head-mounted display. This distortion is necessary to correct the video due to the optics being used. Any advice on a module(s) or examples that already do this?
