Meimi stands for Multi Effect Interactive Movie Interface, and is a real-time video warper. I'm not sure if it also supports live video capture, but I think so. I had no trouble installing it, then I loaded up 20 or so digital video files which auto sequenced as I applied various warping and multi-window effects. I didn't entirely understand what I was doing, but it sure looked cool.
