This is what I imagined, when I started seeing those color changing car paints.
When you look at a piece of paper from the side, you only see a .004" line, but when you look at the face of a piece of paper, you se the 8.5" by 11.0" sheet.
I thought that color changing paint had tiny pieces of colored flake, that when painted on, were sprayed at an angle that forced the flake to all align on the same 3 dimensional plane. Then, each additional color was sprayed on at from a different angle, which also aligned the flake differently. So, when you look at the object, you can only see the flakes/colors that are facing your eyes at that angle. I've even wondered if people used magnets to align metal flake in car paint.
like the man says...if you're swimming in the ocean and get bitten by a shark, its not a shark attack. You're in THEIR neighborhood. If you're at home in your shower, turn around and a shark is in there with you...THAT'S a shark attack
