AAQR: PSwirly (LWP, free)

PSwirly has particles (read: sprites) of various colors swirl around the screen in patterns. There are over a dozen different "particles" available, from simple shapes to Android, certain logos, and more.

Somewhat interesting, but not THAT interesting.

Rating: Try it (leaning toward "meh")
