I’ve been experimenting with how Flash and FlarToolKit handles multiple patterns using FLARMultiMarkerDetector . Thanks to the guys at Squidder.com for sharing their source for the virtual drum kit. I was able to revisit my spaghetti code and improve performance 100 fold.

The MD2 models are from Polycount.

One thing I've noticed, is that if you cut the patterns out or are displaying them on a an iPhone it seems you have to leave a white margin in addition to the black border for the pattern to be recognized.
