Abstract Shape Generator
Abstract shape generator: circles, half circles, triangles, bars and squiggles scattered at random in three colors. Roll a new composition, save as PNG or MP4.
What does the abstract shape generator make?
Compositions of simple flat shapes: circles, half circles, squares, triangles, quarter circles, rounded bars, squiggles and crosses, each in one of three colors on a plain background. Some are solid and some are outlines.
It is the look of Bauhaus posters, built from basic forms in primary colors, and of the Memphis Group's playful 1980s designs, which the Bauhaus and Memphis presets start from.
How to make a random abstract composition
Shapes sets how many there are, from 3 to 40, and Size how big, as a share of the frame height. Each shape's kind, place, size, turn and color comes from the Seed, so rolling it gives a new composition and keeping it brings the same one back.
Outlines sets the share of shapes drawn as outlines instead of solid, and Line their width. The shapes are laid down one after another, so later ones overlap earlier ones.
Can I use it as a moving background or a drawing prompt?
Yes. Drift makes the shapes float and turn slowly; record that as MP4, WebM or GIF at 720p for up to 30 seconds, or set it to 0 and save a still as PNG, JPG or WebP up to 2048 px.
A still makes a backdrop for a poster, slide or post, or a prompt to draw from: roll the seed until a composition suggests something, then sketch over it.
