So I emailed Melanie about the live design and this is what she said..

A live design is a performance - a performance uses the stage, and actors. When you think of performance you think entire play, but this is a ten minute play. You have a story or plot, and you generally use sound. Obviously you are not going to be building sets, but you will use props. Your group can create whatever kind of performance you like. Last year the groups live design included; a rave, slam poetry, and short performances. If your group needs help, please see Alan right away.

I was thinking we should meet on Sunday to figure something out for the live design.
