3D Prints
Hard things that move. Gear balls where turning one face turns all the others, cones that spin whichever way you set them off, little spheres and eggs that twist open into a spiral and close again. Then the articulated ones: octopuses, cobras and starfish with joints running end to end, so they curl, droop and ripple when you lift them.
Every piece is printed in a single go, so nothing is glued and nothing is assembled. The joints simply work the moment it comes off the printer.
