Is there any library for creating animated presentations? Although the question is language-agnostic, I'm specifically biased towards WPF, yet I wouldn't mind you giving examples of libraries for any other language, or a visualization language of some sort.
I know some folks, including Turing Award winner Alan Kay, that use Squeak for presentations. Squeak is an interactive programming environment. It combines objects and all the pleasures of a modern language with the immediate feedback of what-you-see-is-what-you-get document editors.
I donnu if there are tutorials on building presentations with Squeak though.
Dan Ingall's Lively might also be of interest for you.
