A new version of the classic Rattleback puzzle. This is a so called "impossible object", that has its origins in the Aboriginal culture. When you spin it clockwise it rotates normally. When spun counterclockwise, it reverses direction (or the opposite way around, depending on which way the turtles are facing). The objective is to try to explain why the rattleback reverses direction, how is this possible? Handpainted. Design: Vladimir Krasnoukhov & Anatoli Kalinin.
