Homemade Lego-based felt tip pen printer

Based on the number of YouTube views, this video might be old news to some, but I hadn't seen it. Check out this completely home-made Lego-based printer complete with on-board Lego people!

A small snippet from the YouTube description:

Lego felt tip 110" printer connected to an Apple Mac. This is not mindstorms, I designed/built/coded it all from scratch including analog motor electronics, sensors and printer driver, the USB interface uses a "wiring" board.

Here's a link to the post on YouTube with an extensive FAQ section.
