This is a video of the astronaut sculpture created by ex-physicist (once a physicist, always a physicist in my opinion) and artist Julian Voss-Andreae. It’s constructed of cross section slices of mirrors, and almost seems invisible when viewed directly head-on (or back-on), but appears more solid as you move around the piece. That’s cool, plus the mirrors make things behind it appear to travel in the opposite direction. Trippy! And if there’s one thing about space, it’s trippy. If there’s three things it’s trippy, dark, and lonely.
