Ideas for teen getting room redone?!?!?

Okay, so I'm getting my room re done for my birthday. Money isn't really an issue as my stepfather is wealthy. The only things that I have on my list right now is: wireless speakers (not expensive ones, cheaper ones), a glass table to put infront of my TV that's on the wall for putting my Apple TV box and PS3 on, a mini fridge (he owns a lot he owns a pawn shop), and I think I want my ceiling to be completely made of posters. Like the ceiling be covered in posters. Lol.... Anyother ideas? And do you think that the posters on the ceiling would make the room any darker? I like having a light, brither room, not a dark one.
