PhotoPearls for linux
On my birthday a friend gave my the PhotoPearls set. The application which generates the images is only for Windows But I was able to install and run it with Wine. After a while I got stuck when it required a printer to print the generated image. Since i really wanted to try this i had no choice but to write my own application, gPearl. It runs on all platforms that support Python and the Python Imaging Library. More information about the project can be found on the project page.
