Help Me Snaz Up My Cubicle

I am a cubicle jockey. It's not so bad, really. Our office has this great industrial vibe with high ceilings, open ductwork, stained concrete floors and modern accoutrements. The thing is, there's this support beam about 15' above my desk and I think I'm missing out by not hanging something from it. It needs to be something non-electrical and simple/light enough that I can hang it myself with fishing line or light cording. Imzynauts, your ideas please! (All ideas are welcome.)
