I just got a black light with these floresant (sp?) alien heads on metal poles. In the dark with the light on, you can't see the poles and looks like heads are just floating there. It's pretty cool.

I have a lava lamp too, but haven't bothered finding a new heat lamp for it, so it's just in my closet, going unused.

Other than that, nah, I don't have marijuana posters and clothes advertising that I'm a toker.
