Lots of fun toys at http://bighugelabs.com/flickr/. I can see that students would love to play with these. I think the key to successfully using them in class is to have clear expectations for the expected product that students are to create.
Personally I created a comic strip at http://stripgenerator.com/. I decided to make my class opener (their initial writing assignment when entering class) more interesting by putting it into a comic strip. Here it is http://stripgenerator.com/strip/195156/. It is simple, but engaging I think, when compared to it written on the whiteboard.
Future uses that I might use are to have students take pictures of their projects (pop bottle rockets, hot air balloons, balsa towers, etc.) and then create a movie poster or other application showing off their work. Maybe have some artistic students create their own comics for the school newspaper.
