What are some cute teen room idea's?!?!?

I'm redoing my room, and I need more idea's! I just got a new bedspread and it's black and white, with a little pink. I thought I would paint one wall with chalk board paint, and leave the rest white. I've got a lot of pictures that I need to do something with. Oh, and I thought a hammock might be cute, but I don't know where to find one. Any thoughts on wall decor, lighting, rugs, ect.?? And what store/website could I use?
