One thing I once tried that I thought would be really cool, that I just want to warn you about in case Joe C. is still concerned about his precious wall carpet:
You know how sometimes fans line up a big row of K's for each strikeout? Back in the mid-aughts, the women were exceptional at hitting 3 after 3, so I was like "Hey, how bout a big line of 3s along our little baseline area?"
After the third for the fourth three went up (in like five minutes, hehe), a yellow shirt came over and asked me to remove them. Even though I was tacking them up, Joe C. was apparently worried that I was using masking tape, which would damage the wall carpet
I love signs though and the experience didn't dissuade me, heh. I had a Pac Man sign with our Big 12 foes as the little blue monsters to go with that "Eat Em Up" chant, a giant 3, and my personal favorite:
Side 1: We love you Coach Coale (smiley face)
Side 2: We do NOT like the refs (frowny face)
I brought this to a Big 12 tourney one year in KC, and the municipal auditorium security, notoriously a No-fun bunch, was not happy. An old lady came up and said "Do not hold up the other side of 'We love you Coach Coale.'
(sherri got a T that game, so you know the refs were BAAAAD and the sign was getting lots of use)
A few years before that, we created a functional "SUK-O-METER" to track Baylor suckiness. Basically, cut a slit down the middle of the sign, fold a piece of signboard between the slits and slide it. Municipal Auditorum mafia hated this one so much that they even took away our nice-nice signs too.
