Makey Makey is my best friend

I took a couple of foot pedals from my rockband drum set and another from a keyboard I had. Hooked them up to the makey makey, and instantly was able to walk around while sitting in my chair.
Should be able to make just about any type of physical controller I can dream of.
Also, since it's an arduino at heart, it's both cheap and fully programmable.
Got mine for 25$
