The jiggling is probably because, unlike the SETI@home site, this one is actually a screensaver. For those who remember the dark ages of computing, if you left your computer on after logging off, the flashing cursor and steady C:\> (or A\:> for the real oldtimers) would eventually burn out the phosphor on your monitor screen. So somebody invented the screensaver, a little program that kept images moving on the screen when the computer was not in use. Hence, the jiggles. I imagine there might be a way to turn it off.

Just a side note to say that while I like this idea and think it may be helpful, when you think about cancer it's important to look at the big picture: causation (smoking, pollution, nasty chemicals in our agrocorporate food supply, commercial-driven nutritionally wretched foods in our diets and especially our kids' diets, etc.), better access to health care, and a broad-based approached to prevention and treatment rather than the "let's find the magic molecule which will get rid of all cancers so we can all keep trashing our bodies and our environment and not worry, tra-la" approach. All of which is not to belittle the amazing success modern medicine has had in prolonging and improving the lives of those who have cancer--just trying to provide some perspective. OK, soapbox off.
