Over on aniboom.com (the animator) there is a very nice tool for creating animations out of black and white geometrical shapes, the resulting animation unfortunately cannot be embedded in other websites. It made me wonder if the same effect could be achieved using powerpoint. These are the frames of my first attempt. I added the lot to jumpcut.com as an animation which can be embedded anywhere. I also tested them with unfreez which is a tiny free program for creating simple gif animations.
