Darkware's mystery animations.
Ok guys, here's a zip file that has 19 images of a repeating animation I made. Once you download it and unzip it, Open the animation in fcheck. Here's the catch: You have to figure out how I did it with expressions only! And it wasn't any big project, either. It took about 10 minutes to complete. Here's a hint: You can't see all of the geometry used.
