Summary for curated list of code CAD (not a bug report)

[Irev-Dev]

Hey Doug 👋 ,

I finally got around to putting together a list of all of the code-CAD projects that I know of here, and also on Github.

I've put a short summary of each one, but it's hard to do them all justice. for curv I wrote:
Curv is a programming language for creating art using mathematics. It’s a 2D and 3D geometric modelling tool that supports full colour, animation and 3D printing. It was inspired by OpenScad and shadertoy.

If you would like to give me a summary of the project, and perhaps some points of how it differs from other similar projects would be happy to include it. I think max three paragraphs would be about right. Open a PR on reply to this issue and I'll include it.
