Jehan Pagès, one of our active contributors, started a personal crowdfunding campaign to sponsor his work on symmetric painting in GIMP. You can find more information in his blog, and there’s a video of a proof-of-concept implementation on YouTube. If you care about GIMP as a tool for digital painting, supporting this project is likely to benefit your workflow.
While we are not ready for a full-fledged crowdfunding campaign for GIMP yet, we think that this kind of focused campaigns, tailored for particular audiences, definitely have merit.
