I love collecting pictures of interior design, just for inspiration purposes. And since I have a 5 year old son, I like to see what's out there in the boy's room designs. These are some of my favorites.

The first one is a wall mural of Napoleon Dynamite hand-painted by Gabrielle Blair (better known as Design Mom). I am so in love with it, especially knowing that it was especially made by a mom just for her tween son.
The second design I find very scandinavian, and I love everything scandinavian :) This design I found on Stephmodo's blog a couple of weeks ago.
And the third design, I think I found it on the Living Etc website (but it's been a while so I might not be right). I love the bed and the colors of the wall.
