The Theremin. GrantBob brought it in. It's something he just happens to have. It's pretty amazing. Some of the things this man has is pretty amazing. Who would have thunk, he has a Theremin.
Being a musician, I really enjoyed it. It was much different than the usual wind and string instruments I play. I bet though if I had it for 30 minutes I could play songs and really make some music with it.
