I ran a 3D Photo Booth at the 2012 Pittsburgh Mini Maker Faire back in September. While not nearly as cool as the one in the article, we did scan over 90 people over the course of the day and print out over 40 at the fair with two makerbots.

We couldn't have scanned so many people without some automation for streamlining the scan process and cleaning up the scans for printing. I posted the rails app we used and automation scripts on github:
