The developers working on GIMP, a popular image editor/Photoshop-replaement for many OSs including Linux, have created a blog where they are posting submitted images from anyone who has ideas about what the new GIMP UI (user interface, the buttons and stuff) should look like. I hope this process turns out a really great UI, and I think it will. One of the things that, in my opinion, Linux applications sometimes lack is a good/original UI and I think this will fix that problem.
