I took my Christmas signature from last year and made it into an animated kaleidoscope.....good grief, Charlie Brown, I can't believe how quickly I forgot how to make one of these. That's the price of getting old, I guess! *Rolls eyes*
I used GIMP and the GIMP Animation Plugin (GAP).
If you have the Mehdi kaleidoscope plugin, this style would be created by taking an image, giving it 6 petals in the Mirror effect, and moving only the Vertical slider.
