I like this, too - like having a huge selection of random screensavers, it's great attention grabber for people wandering by my desk.

Just one question - should explicitly selecting a new visual turn off the random switching? I was a bit surprised that the visual I chose turned to something else at the end of the track. I'd prefer it if Random was treated as a mutually-exclusive choice to the other visuals (several choices, really, since there are different Random Visual modes), in the same way that Funnelweb is mutually exclusive with Casualty. What do the rest of you think?
