Yup. I'm a big fan of BuckyBalls. They rock. I have 12 sets here at work that I build with while on conference calls. I think that when you go to work for Fedgov, your brain has to be checked into a safe deposit box or something to make sure you won't interfere with their insane policies.
BuckyBalls are definitely not for small children, but then again, neither are many other common things that people use every day.
