I spent the majority of my holidays studying art and watching videos and I thought I'd make an entry here devoted to collecting urls.
Some links are NSFW.
I'll edit this and add more as I get time, Reply with links of your own - do not reply without a helpful, or at least pretty, website

The following are all tutorial or reference sites. I may append pretty or inspirational stuff later.
Videos

A collection of fine art documentaries.
