GIMP needs no introduction. GIMP is the Open Source answer for Adobe Photoshop, well, almost. We had already featured brilliant wallpapers made using Inkscape and now things are taking a 'GIMP' turn. Here is a nice and simple collection of wallpapers made using GIMP.
#GIMPies@deviantart for the wallpapers. Please do bear in mind that, I have tried my best to be accurate as possible. If you want to know the exact tools with which these awesome wallpapers were made, visit respective links and ask the author himself.
