I thought this website was sort of interesting/funny, you are able to pick from a set of characters, backgrounds, sounds and other items to create a custom movie, you can add motions, hand signs, face expressions, a background image on a wall, you can also move the camera. You add in your own text that the characters read and interact with and they actually get the words typed in pretty well, even words that are not really in the dictionary. You can then publish your movie to any of your social networking sites and tag the movie whatever you want so it can be found using their search box
Here is a good architecture one:
Why i thought this was relevant? well just thought it was an interesting interactive program that was created by someone (which im sure was sort of complex) but made it easy for us to use.) The interface itself is pretty easy to use.
