I would have to respectfully disagree with the floormat idea.
If you watch stylenetworks home improvement shows there's so are "thangs" you can do with that floor mat. Just b/c it's a floor mat doesn't mean you put on the floor for folk to step on.
I have a floormat that's over five years old and I've never stepped on it.
You can frame it for wall deco. If you don't watch stylenetwork, please do. I'm a stylenetwork junkie. I watch that station probably more than any other.
I do agree with the keychain and the t-shirt thang. I only get Boule T-shirts or ones that have a more afro-centric appeal to them. At a regional conference I saw a key chain that I really liked for another organization though

. I told the vendor to make one for mine, so know telling how long that will be.
