Smart design: kids' room
Wired's GeekDad blog has some pretty great posts. This one in particular caught my eye: it's about creatively converting a plain IKEA bunk bed to maximize the amount of space in his kids' room. The result was so kewl! I'm sure the Dude would have loved us to do something like this in his room, although it would put one of the beds across a window... :)
Check out the whole post where he describes the process to make this happen.
