I like this effort. I cannot stop messing with the presets to find new effects. It does make me want to go out and get a new graphics card. I am running a MDD 2 x 867MHz with 1.5GB RAM but the graphics card is the stock 32MB video RAM. I guess it isn't enough for my two monitors, because most setting result in an unacceptable lack of smoothness -- the motion is jerky. The jerky movement makes the screen saver unusable as a day-to-day screen effect.
