This is a kaleidoscope created with ScopeWorks, a kaleidoscope generator for Macintosh which is available on the Mac app store.
The source image for the kaleidoscope is a fractal image created with FractalWorks, a high performance fractal renderer for Macintosh, which is also available on the Mac app store.
Both apps were written by me for WareTo LLC.
The fractal in this image is a 3D rendering of a Mandelbrot set fractal. If you have FractalWorks, you can recreate the original 3D fractal image by clicking on this link.
