Sail
Sail is a generative art framework. It’s not designed for anyone to use. Sail exists to make it simpler to play around with new ideas and render new pieces of artwork.
It’s all open source, feel free to fork it if you want to. It currently only renders out PNGs, a flaw I’d like to fix in the near future.
It currently uses fogelman/gg under the hood. This may change as it doesn’t support SVG or PDF rendering.
You can see some of the images generated by Sail on the Artwork page.
