Blender, when combined with programs such as GIMP, Ink Scape and NVU make for a fairly complete design setup. Blender is a three-D design tool. GIMP is like Photoshop while Ink Scape is like Illustrator. NVU is a web design tool, like Dreamweaver. I've used GIMP and found it to be quite usable. Some of the features are beyond me, but then so are many of the features in Photoshop.
