A simple graphical demo for the PICO-1K Jam 2025 which creates an animated Dragon Curve.
A Dragon Curve can be generated physically from repeatedly folding a strip of paper in half and hence the lines in a Dragon Curve never cross each other.
The different colours represent the level of recursion that each segment was generated at by the algorithm.
You can use the cursor keys to move he viewport and ZX / NM / CV to zoom in and out to explore the curve in more detail as it renders or once it has finished.
The compressed byte size of the cartridge is 643. I've made very little effort to save bytes because the program is so simple in the first place.

A simple graphical demo for the PICO-1K Jam 2024 which creates an animated pattern similar to the spiral pattern that seeds in a sunflower make.
I'd played around with this in lockdown using Java libGDX and decided to port it to PICO-8 for the 1K jam.
You can use the left and right arrows to change the radius of the dots.
The compressed byte size of the cartridge is 312. I've made little effort to save bytes because the program is so simple in the first place.
