The Kid Should See This

A cube and a heart made from paper gears

Japanese paper crafter Haruki Nakamura designs mechanical paper karakuri-style animals and other paper automata. In the silent video above, he creates a cube made from 12 interlocking paper gears.

Nakamura has also created a paper gear heart, as seen in the video below.

He sells the 3D printing data for both the cube and the heart. See 3D printed versions of the heart, cube, and a rabbit in action below:
