This Is a Useless (And Awesome) Machine

Man, I love the concept of these “useless machines.” Each one is essentially a small box with one switch. When someone flips the switch, it triggers a hand/finger whose only function is the turn the switch off. Brilliant.

This particular useless machine has an extra surprise at the end. Make sure to stick around until the end!

I still haven’t played at all with the small Arduino kit that Liz got me for my birthday. The idea of making small little magical boxes like this is really appealing right now…
