Is this in anyway similar to Turtledraw? Looks like a similar concept (programming the maths to make a turtle draw graphics). I’ve seen a load of different implementations, from something similar to Logo (where it’s drawing on the screen), to where it’s drawing using a physical robot with a marker pen and a big sheet of paper on the floor, to a variation called Turtlestitch which controlled an embroidery machine.

I spoke to a woman at a conference last year who uses Turtlestitch to teach 7 year olds advanced programming paradigms.

Wasn’t there also very recently a whole thing about the single guy who maintains the NTP spec threatened to retire so he could get a “real” job, which caused a gigantic internet-wide panic as pretty much everything we do relies on computer’s clocks being perfectly synced?
