Retrograde is an original piece, a sort of space odyssey. It reminds me of the images of galaxies we see from our telescopes looking into deep space. The underlying algorithm is based on a Lissajous curve whose parameters are filled with random numbers controlling their frequency, size and opacity. Multiple curves are super-imposed to form solar systems. At intervals along each curve are circles (planets), representing instances of a celestial body in motion either forward or retrograde.
To add to the cosmic vib there are 5 possible celestial backgrounds: 4 randomly colored color linear gradients drawn either top left to bottom right or top right to bottom left as well the possibility of solid color with a 25% chance of white. Each image generated is a fantastic galaxy of color.
