Dolphins fly gracefully among delicate reefs as a watery melody plays. The only thing missing from 3D Dolphin Reef is the familiar chirping dolphin song. You can change the number of dolphins, the time of the day, and the tint. But be prepared: the music doesn’t stop when you exit the screensaver. Also, since some parts of the image don’t change, older monitors still susceptible to burn will not have their entire screen saved. Nag notices abound, but the dolphins are charming.
