This is probably one of the coolest things I’ve seen done with PD. It’s stuff like this that make a little more sense as to why PD was created. I knew PD could make use of your web cam but I’m not sure what the kid was wearing on his fingers and how PD picked up on it’s movements. Although the sound was a little harsh I could definitely see this perfected and even marketed as some sort of new game. It would be fun as hell, it’s like an in between guitar hero and playing an actual guitar.
