I had/have a bunch of random stuff (think beer and pinball) up on my walls which looks about like that, random. I had hoped to make it look pretty cool with the sheer amount of randomness but have come to accept it as a bit of a fail. I am now in the process of hiring a mural artist who is going to paint all of walls in the room so that could be another approach. It should be done in a couple weeks but everything is coming off my walls it will just be the paint. It's not cheap but when you add up the cost of a bunch of framed hangings it actutally isn't too bad. I don't have the final design yet but it may be based off fathom artwork.
