This is great, thanks for sharing! I wish I had known about Sol when I used to teach high school geometry; the fact that many of these constructions can be interpreted pretty openly would have produced a lot of different "answers" and opened up the floor for conversation about rigor.

Instead, I had my students construct the flag of Nepal (see http://www.servat.unibe.ch/icl/np01000_.html for the specification). Let's just say that most of the students were not as captivated by the idea as I was.
