Time & Motion
The illusion of motion is quite interesting. Depending on the purpose of the image, it can illustrate the point much better than an image where everything looks still (such as a photo of a dancer. The very essence of a dancer is movement).
Storyboard project for university. Team members created the imagery for the story, and I animated it in Flash. Coming up with the timeline overall, and timing each little piece of every image to work together and create tension and tell the story was a challenge, but very enjoyable.
