I'm going to attempt to replicate this in the very near future. The boys are all about super heros right now, so I think it's time to hang up the space theme and move on. I'll make two with Batman, Captain America, Iron Man, Cyclops, WarMachine, Wolverine, Spiderman,and Magneto.
Perfect for a kid's room (decorate shelves however you want)! Maybe put next to bed for easy clean up after nighttime reading? Could do this with superhero symbols, or princess colors, etc. Great for saving room vs. the traditional book shelf.
