Well, actually can be any color…
This is just a great optical illusion. Just download THIS PDF file and print it (the bigger the better). Cut and glue following the simple instructions.

Doesn’t matter how much you move side to side (or even up and down), actually the more you move, the more outstanding the effect is. His head and eyes will always follow you.
You have to close one eye and only start moving afterwards, otherwise it does not work. This effect is due to the brain getting the wrong clues about the dragon’s head shape, which is actually concave. Give it a try, or be lazy and print it for your kids to cutout and glue. It’s really an interesting effect.
