Do any of you play the theremin? I've always liked the sound, but I never bought the instrument. A friend bought a MOOG Theremin (over $300) a while ago, but she never could make music with it. She gave it to another friend who plays several instruments, and he was also unable to make it sing. Like most other activities, it looks easy when someone else does it.
You'll recognize the sound from many sci-fi movies.

The instrument was invented by a Russian scientist named Leon Theremin while he was working on a project for the Russian government. He did quite a bit of traveling with his instrument, and he was a spy for Russia (USSR).

Sidenote: I remember hearing about this -

"Theremin invented another listening device called The Thing, hidden in a replica of the Great Seal of the United States carved in wood. In 1945, Soviet school children presented the concealed bug to the U.S. Ambassador as a "gesture of friendship" to the USSR's World War II ally. It hung in the ambassador’s residential office in Moscow and intercepted confidential conversations there during the first seven years of the Cold War, until it was accidentally discovered in 1952."
