I had the occasion recently to look into Monge's theorem and stumbled into his work on drawing 3-D objects in 2D. It is that sort of late 18th century stuff that portends projective geometry and is well worth looking into, I think. There are a lot of those techniques that are very relevant nowadays.
http://en.wikipedia.org/wiki/Descriptive_geometry In dealing with circles, I also found out about the problem of Apollonius of Perga (272-190 BC) who showed there were eight distinct circles tangent to any three non intersecting ones. http://en.wikipedia.org/wiki/Problem_of_Apollonius The SVG drawing illustrating the eight circles at the Wikipedia page is quite cleverly drawn (though the code could be greatly simplified!). The questions of how to make Venn diagrams that make the intersections maximally distinguishable to the [typical] human eye is a fascinating one that has received very little research (unless it has been done in secret!). I didn't learn this sort of geometry in school, so it's quite a bit of fun!
