Volcanos

This screensaver does boast its share of pluses, but due to the demo's tiny picture library, we'd guess most users will quickly lose interest. As you might expect from its name, this program displays shots of active volcanos. Unfortunately, the demo only lets you view three shots: two close-ups of lava flows and one overhead view of a crater. Image quality appears to be decent, but three images isn't really enough to make a conclusive judgment. One thing we definitely didn't like was the cheesy, inappropriate MIDI music, which sounds like a Scottish bagpipe tune. However, Volcanos does have plenty of features. For instance, you can tweak the speed of the transitions, set the interval between images, disable the music (thankfully), and enable a border effect. In addition, you'll also find a tool for building your own screensavers, though you are still limited to three photos and MIDI music. Geology and earth science buffs might find the full version of this program worthwhile, but this demo will be a bit too limited for most.
