sorry ~ the old gimpstick forum went down.
GIMPstick is a bootable usb with gimp on it. and that's it. in it's pure form at least. in it's dirty form, it has a whole host of other tools to either help or hinder with distractions. with pure, there's no distractions, just GIMP.
GIMPstick 3 dirty is out!
sorry, no pure release at this time, they take more work (weird, i know).
i havnt even tested it. lol. i'm sure it works. i trust slitaz and tazlitobox.
