The Digital Artists' Handbook - http://www.digitalartistshandbook.org/ . Description: "An up to date, reliable and accessible source of information that introduces you to different tools, resources and ways of working related to digital art." This has been put together by folly (http://folly.co.uk/), a digital arts organisation from the North West of England. The emphasis is on open source software (the Gimp, Blender and Processing for graphics/animation/interactive animation, for example), and it would be useful to have more detailed point-by-point comparisons of open source packages with their closed source equivalents, but all the same this is an extremely useful resource.
