This is a kaleidoscope based on a fractal image called Dec30mma1a created by another fractal artist named Kent Schimke. I zoomed in on a portion of Kent's image, brightened the colors, and adjusted the lighting slightly.
If you have the current version of FractalWorks, you can recreate the fractal used to create this kaleidoscope by clicking the link below:
