FluxChallenge #1

[hsavinien]

Today I read a little about the Fluxus movement.  This is (probably) not that, but it is inspired by it, particularly Alison Knowles' version. 

Every day, for as long as I can keep it up, I'm going to put up a challenge which I will try to complete as well.  If you feel like doing it, respond (within a couple of days).  Your response doesn't have to be any more complicated than "Me," "Done," or anything like that unless specified.  It's just to make you think.
