I know I rarely carry change, especially not nice hefty quarters. They 
burn holes in my pocket.

But a little ziploc bag of 8 coins takes up less space than a roll of 
tickets, probably costs less, and works for up to 256 people. If you go 
past that point, *somebody* is bound to have some change.

There's nothing remarkable about it. All one has to do is hit the
right keys at the right time and the instrument plays itself.
