And I thought our platform treehouse was cool when I was a kid! This enterprising geek dad turned two shipping crates (and a buttload of lumber from Lowes) into a BattleMech robot treehouse. Took him seven months. The truly geeky thing is that his kids don’t play MechWarrior, *he* does.
I can just hear the conversations with the wife: "I know I’ve been in the garage for seven months, honey, but it’s for the kids. Think of the kids." Yeah, right.
