As far as I know, Koen Beets is the first person to build a camera out of Legos from the directions I posted back in November. I was glad to learn about some of the tweaks Koen made to his version of my medium format Lego pinhole camera. Most notably, he was able to make it light-tight without using any tape! His solution was to make the walls four bricks thick. It looks pretty cool, and Koen has taken some pretty cool photos with it, too. Go on over to stuutekeer.wordpress.com and check it out.
