Here’s a first: someone managed to create a functional “3D printer for chocolate” using Lego bricks. Demonstration after the jump.

From the article: “There are only 3 controllable ports on the rcx brick i used, so one for x, one for y, and one for the extrusion control. you’d need to gang two rcx bricks to further control temperature and the z axis.”
