Some number of circles, each with an orbiting set of the same number of smaller circles, orbiting a larger circle.
What appears to be a spinning series of dots with interesting radial patterns but is simply a changing number of dots placed in a slowly expanding fashion using simple trigonometry.
Overlapping repeated polygons with varying sides and colors that resets after variable numbers of polygons are placed.
A somewhat chaotic slowly warping grid of various polygons, each of which is one of two color, filled in or not, and spinning or not.
A spinning polygon of varying sides shoots out of a slit in the screen before gravity calls it back down, only for it to disappear for all time and another to be born and start anew.
A spinning polygon that has a circle tied to each vertex. A server far away impacts how much the polygon spins, how many sides it has, and other environment factors.
Some approximation of a very slow simple sketch. Intended to be presented for long periods of time, like on an Electric Objects.
