This reminded me of those booths they have at company holiday parties where they take a photo of you, convert it to a line drawing and have the robot draw it out for you to keep. Very cool hack!

This thing is basically a small pen plotter for kids. Would love to see it do a more complicated design.

super cool teardown

Normally we'd email a repost invite for these (see https://news.ycombinator.com/invited) but I was unable to do that in this case. I hope this is ok!)
