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 – <a href="http:&#x2F;&#x2F;www.math.ubc.ca&#x2F;~cass&#x2F;graphics&#x2F;manual&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.math.ubc.ca&#x2F;~cass&#x2F;graphics&#x2F;manual&#x2F;</a> <a href="http:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20140326124027&#x2F;http:&#x2F;&#x2F;www.fho-emden.de&#x2F;~hoffmann&#x2F;pstutor22112002.pdf" rel="nofollow">http:&#x2F;&#x2F;web.archive.org&#x2F;web&#x2F;20140326124027&#x2F;http:&#x2F;&#x2F;www.fho-emd...</a> – it’s a fun little language.)<p>Otherwise, nope, this thing doesn’t have too many features. Looks like someone’s little hobby project.<p>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.
