You may be wondering how to make one of these wall murals yourselves. You can find great tips and how to's on a couple of websites here, here, and here. Personally, I like to just lay all of them out on the floor, reorganize, and then work from one end to the other hanging them up.
I love having this wall in our apartment, it creates a great dynamic and adds color and character to the room and overall feel of our apartment. Maybe you should consider doing this in your house. It draws comments from every single person who sees it. I'm very happy with it.
p.s. don't mind my nasty post dance clothes self
