Kaleider Screensaver provides you with a funky psychedelic screensaver experience featuring Kaleidoscopes, Mirroring, 3D Mirroring, and Funneling effects automatically in random sequences.
The Kaleider Screensaver configuration screen offers many settings and allows specification of which effects and how often it uses them. In addition to the random effects, you can also include scripted sequences if desired. The images' source that the effects are based upon can be set to an image directory or image gallery. Kaleider effects can also be accompanied by music from the audio options section of the configuration screen. The source is either an audio directory containing MP3, MIDI, etc., format files, or an Audio CD. You can get as trippy as you want, perhaps some Grateful Dead.
It does offer to make Kaleider your default screensaver.
Kaleider Screensaver also will permit you to create and save multiple Configuration Files with customized settings and personal image galleries. This package includes the free Kaleider Screensaver, along with a collection of sample photos to serve as source images for Kaleider effects.
A fun screensaver visually, but with enough configurations to play around with to keep it technical - but not overly.
