Hi! I'm the author.

Like jchw said, this was a single-day project (although I did the writeup for it the next day).

I went from 0-prototype in one sitting; I think that was around four or five hours of work? Then I went home, had dinner, and spent maybe three hours optimizing and cleaning it up.

edit: I should say, i have done a lot of dumb things like this and I'm pretty sure it would have been at least a week of work for me 2 years ago. "making the computer do dumb stuff" is a skill like any other!
