A beautifully rendered high res pterosaur from the Jurassic period soaring through high res canyons and mesas accompanied by pterosaur vocalizations in the background, the sound of flapping wings and air currents along with sun flare. A very esthetically pleasing screensaver....this is eye candy very well executed. And at just $6 it's well worth it, I think.
Definitely, one of the better quality screensavers out there.
