Projected shapes with some drum interaction

So I just completed my first Touchdesigner project a few months ago. We created People Beats for the Beams 2015 festival in Sydney.

It involved projection of abstract animations, images, and video footage onto shapes that were attached to a wall. People could hit drums and it would change the animation being projected.

And thanks to the community a few months back for advice on how to get lots of sounds triggering over each other.
