Graphic software
  • Blender: open-source 3D software.
    Very fast, light, rock-solid, full-featured, can compete with very expensive software in most situations;
  • Gimp: open-source 2D image editor.
    Complete and powerful, but not so good as its famous and expensive competitor (not yet?);
  • Sodipodi and Inkscape: open-source 2D vector editors.
    Inkscape was born from Sodipodi, and now is being developed much more actively. Neither is complete and full-featured yet, but they are both powerful and very pleasant to use
