High Speed Photography

We just finished our Split Second project in my photography class and (isn't it always the way?) here's a great page I just found for some beautiful high speed shots of various things getting shot (both meanings of the word) on Weburbanist.    Of course, I made it clear that while I wanted the students to feel creative to explore ways to capture something that would not be seen with the naked eye, under no circumstances were they allowed to shoot things.
