Buy A Used Couch (With holes) , A Box Tv, Dirty Rug, A lock for the room(deadbolt), A black curtain for no light, A black light, A disco ball, and a microphone + Sing Star....
Looks nice. I'm not digging all that light though. It seems a bit overpowering. I'd be the guy who would get some thick window treatments just to block out all that natural light lol.
