This is from the Spiral Curve animation, created by animating spline curves with color gradients in a spiral pattern.

This is from the Spirit Body animation, which is created from mirror images of two animating spirals.

This is from the Spiral Square animation, created by animating rectangles with colors moving through them in a spiral pattern.

This is from the Rays animation, created by laying down thousands of dots whose color is determined by its position and angle in a tiling pattern.

This is from an animation called "Rain". It combines a random leaf generating algorithm with circles that distort the image underneath to create the impression of water droplets.

This is from the Squares animation. This one is based on a square grid pattern and colors dots based on prime factors of dot locations.

This is taken from the Waves animation. The splines move up and down like waves and the color gradients are based on the angle of the curve at each point.

This is from the Dot Mandala animation. It is created by drawing dots along a curve, with the dot color being determined by the angle of the curve at the dot location.

This is from the Trees animation. The trees and leaves are drawn with a fractal algorithm.
