It’s probably a bit easier to learn than MetaPost. (For just drawing postscript drawings, you can do AMAZING things by just programming in postscript directly – http://www.math.ubc.ca/~cass/graphics/manual/ http://web.archive.org/web/20140326124027/http://www.fho-emd... – it’s a fun little language.)

Otherwise, nope, this thing doesn’t have too many features. Looks like someone’s little hobby project.

What I’d like to see out of a project like this is an interactive JavaScript version, where I can drag around points and see how the whole figure reacts.
