Probably reinvented a wheel, because I ended up with: An orbit trap at (0,0). - intensity/brightness is controlled by orbit's closest distance to (0,0). Essentially, brightness = 1/(minDistance + 1) ignoring the starting Z_0 = 0 value - color is controlled by the specific iteration count where closest distance was reached (selected a "pure" rainbow color, spreading those out with the Golden Angle) Additionally I tweaked the gamma curve to darken the surroundings, and faded colors to white when approaching maximum intensity. Overall intensity range is scaled to image contents, i.e. darkest pixel is always pure black, brightest pixel is always pure white. Title: Re: Happy New Christmandel Bunny!

Congratulations, you reinvented atom domain colouring: http://www.mrob.com/pub/muency/atomdomain.html |
