The Fondation Daniel Langlois has a very cool Flash web site. Everything launches little windows that let you switch from French to English, resize the window, and get a unique URL if you are trying to reference a specific item. This is useful given that the interface is in Flash.
In particular check out Eisensteins Early Drawings (go to the parent block and open the interactive sketchbook). They have an interactive interface for the pages of the sketchbook which is compelling.
