Theremin for the poor man, LOL!

Ever since I found out what the amazing instrument is that the Beach Boys used in their music, I've been fascinated by it.  Little did I know that my new-found fascination with water glass music would also end up acquainting me with a cheapo version of the theremin (tho I hear say that one should not try it except on saws that are at least 20 years old).

Guess this is whatcha call...cutting edge music?
