This Neat Lego Automaton Can Draw Portraits

This is Legonardo, an automaton capable of drawing portraits. It doesn't have the complex clockwork used by automatons of old, like its Swiss counterpart made by Pierre Jacquet-Droz and Henri Maillardet in the 18th century, but it's pretty neat anyway.

Legonardo is made of Lego Technic bricks and powered by Lego Mindstorm controllers hooked to a computer that uses custom programming to generate the portraits.
