I have been diligently looking for cool stuff this week and I am not having much luck. It's slow right now, but it will pick up, so stay tuned. Plus, I have been building and programming like crazy.
And in the meantime, check out this slow kinetic art piece by YouTube user WillemVanWeeghel. It's simply a bunch of tubes controlled by 32 motors. As you watch it slowly move, you can see things. I think it would be a great thing to sit and watch while trying to go to sleep....but not now!
