So it was a mime lady inflating herself with an invisible helium tank I think. Could have sworn it was here but I've searched for "mime inflate" everywhere I can think of with no luck. I can't be the only one who remembers this, am I?
Sounds like an interesting piece if you can find it. You might have better luck in the Artists' Studio board.
