Disclaimer: I would only recommend this for experienced GIMP users. If you're still unfamiliar with basic GIMP usage, I would not advise installing this until you get more familiar with GIMP itself.
I'd like to introduce a very nice GIMP extension to all GIMP users here.
It's called GIMP Paint Studio, and you can install it if you have GIMP installed - it's very easy, you just unpack it to the folder where you have the gimp settings, brushes, etc. - not the main gimp folder that's under program files, but the second folder that's in documents & settings. Well, there's instructions for installing here: http://code.google.com/p/gps-gimp-paint ... stallation
What it does is, it adds tool presets, lots of cool and very useful brushes, gradients, etc. to your GIMP, which are great for painting and drawing.
