1) Image processing can be done using surfarray. For example, a 3x3 mean filter can be achieved by averaging offset arrays of one image. It's quite simple and fast. Glow is just blur done on luminescent objects.
2) I think there's work being done here. I don't know if there are plans to integrate into pygame. Others can comment. 3) AI might be nice, but I think pygame is more of a graphics library. There are probably some good modules of the sort already out there. Ian
