Beep It

Via Chance Shirley, the BeepIt. That's a $35 Theremin-like thingy.
I got some spam mail from BMI about BMI Live (I'm a BMI writer). Presumably you can get paid for performing your songs even in small venues. I can't imagine that the royalties are more than a couple cents per song at a bar in New York but hey, we'll be earning royalties.
