(formerly) GIMP for Windows and Mac with a huge amount of Open Source or otherwise free or public domain plugins. windows version has installer. mac version must be assembled but has zip files. heard some of the plugins went commercial, and I don't know which, so this project is off. please get GIMP from and donate to the following projects (not mine):
Great compillation! Would take days to find and install this! <3
Pros: "GIMP massive package" is a gigantic 'gimp-plug-in-playground' definitely entertaining and worth trying! Cons: - The menu-bar is only fully visible if you have a big screen. - At the moment there are no updates or new versions in sight. - A "GIMP massive package"-Forum or a link to the appropriate forum would be nice.
