No Need For Crabs

I always wanted to have a screen saver like the one used by Washu in the episode "Hello Baby" of the animé Tenchi Muyo! a couple years ago I imagined how I would do it. So, I finally got something that works. It is only one crab that walks along the screen. The plan is to have two crabs walk in opposite directions on the screen at somewhat random heights.
Originally, there is a beeping noise that activated with the screen saver. I am still not sure if I should add this or not. Generally, I don't like my screen saver to make noise.
