Create your own animated artwork with hexagons. Basics: use FULLSCREEN; use MOUSE; TOOLBARS should appear when you move mouse off screen at left (size of hexagon), right (colour picker), bottom (repeat pattern) and top (animation/editing). To select a colour already on screen, click it while holding down "C". To delete a hexagon, click it while holding down "X". (It's a bit slow. Note that the selected repeat pattern will apply to the deletions.) To delete everything and start again, hold down "D" and then press "E".
@PutneyCat I just made an artwork with this and remixed.
