I've always heard that a beard can keep you warmer during the winter months but how can you really know?! After all, if you start with a beard and then shave it off there might be some strange adaptation effect going on. And who knows the memory of cold might be completely inaccurate anyway.…

Maybe it's because I just had a stiff drink - but I absolutely love this thing. The art is cool, bicycles are great, and engineering for fun interests me. Maybe it's not the bourbon... -Via Neatorama-

I'm don't think it's all an optical illusion, only the last part is. There's a decent amount of editing. It's a real 3d cup all the way until the "Where's the ball" comes up. It is a really nice job at printing out an exact replica of a 2d view there at the end however.
