..does anyone have a link to some site that explains the process behind 2d animation? and i would imagine there are a lot of different ways that is done..and some (or a lot) would involve 3d animation to some extent..so links to that sort of thing would be great as well.

anything that explains the process of how something comes together..i am really fascinated by it but i am having real trouble finding some good explainations online

thanks for any help
