Moiré Turning Cards: rotational kinetic art moiré pattern motion on a postcard. The geometric pattern on a transparent top layer is rotated over a similar colored pattern creating the morphing and intricate moiré interference patterns. I found these postcards in the @momath museum shop last week. Made by Bizarr Verlag. ➡️ Follow the link in my profile for info on where to get this and many other amazing items featured here on @physicsfun #mathtoy #moirepattern #physics #physicstoy #interference

Turning Mecard Mecanimals are super cool vehicles that transform in a flash to become gigantic robotic heroes! They are based on an animated TV show from South Korea in which mini cars morph into alien robots. Roll the vehicle onto the front edge of the Mecard to trigger the morphing mechanism. With a thrilling FLIP! the creature hero springs “to life”! Assemble the robot back to a car and repeat again and again. Score attack points on the battle arena in head to head play against your opponents
