XKCD Starfield Screensaver

Similar to the original Starfield screensaver from Microsoft, the XKCD Starfield screensaver makes it look as though you are flying through space, but it adds the idea from issue #1229 of the XKCD webcomic that the probe is bound to hit one of the stars at some point. Once in a while, a collision occurs and the signal from the probe is lost until the screensaver is restarted.
