The fully-functioning Lego air conditioner

Do you like Legos? Of course you do. Legos are pretty much the ultimate toy, allowing kids to build whatever they want to play with. I grew up with them, and they do nothing but foster creativity and imagination. God bless Legos.

That's why it's always fun to see grown-ups still hooked on their childhood obsessions to stunning results. Take a look at this: it's a functioning air conditioner built out of Legos. It's got a spinning fan, compressor, and valves and actually works. I could never have built this when I was a kid, but if I could have I probably would have gotten into a better college. Ah well, regrets.
