thanks man! The geometry is just a bunch of planes moving from point a to point b, but I key out everything that isn't overlapping to create more interesting forms. This was then added as an alpha layer, and I alphablended the same picture over the original but made it a few pixels bigger. I'm going to add some other functions so I can control the image more and add more live elements, but getting this basic functionality was a huge step for me in better understanding how opengl rendering works in jitter.
