I'm no artist. I couldn't draw a stick figure to save my life. But even I would be able to make a kick-ass sketch using this insanely cool, 9-feet tall, room-sized Spirograph by artist Eske Rex. (It takes up 380-square-freaking-feet.)
If you're like me, you looked at this picture and the name "Three-Pendulum Rotary Harmonograph" and felt confused and a little bit threatened. But fear not! Turns out it's one of those fun spirograph-like things you see at science museums.
