TouchDesigner: Clothespin Controllers

I'm silly at times, and I've also been wanting to hack apart an old keyboard for a while and create wires that can easily be linked up to any kind of random little controller to create dozens of momentary buttons. I like the idea of creating an interface based on objects in a room, and I've done this a lot using cell phone accelerometers within physical structures. Now I'm trying to explore other wants to create controllers with various items that might be easy to create.

 

Of course I'm playing with Arduinos a lot, but there are other hacky ways to get things done out there too. This is an example.
