Reply to animation programs similar to ableton or step sequencer?

the VJing article on the main page reminded me of something i always wanted to try out - animation. basic scenario for what i would like to try - with photos or scans of hand drawn material be able to sync at various tempo resolutions a succession of images to midi clock. im not looking to do smooth animation or anything like that i just want to be able to do stuff like take 4 drawings and alterations of those 4 frames and sync it to a quarter beat. almost like a midi synced photo slide... anyone have a suggestion for that sort of desire or does that not exist?
