ChocoFlop was my first serious experiment with Objective-C. It was a nice experiment with non-destructive CoreImage filters. The project was a bit too ambitious for a night-time project and I didn't even own appropriate hardware (my iBook G4 used software, not the GPU!) so I abandonned it. It only runs on older Mac OS X versions (10.4).

I keep a copy of the old site
