Abyssal Lab

Explore the mathematics of deep-sea bioluminescence. Adjust the parameters
across morphology, dynamics, rotation, and appearance to generate unique
jellyfish-like forms. Save your favorite configurations as custom presets.

It is a small laboratory for anyone curious about generative art or how a short formula can draw something that looks alive. You change numbers and watch a creature made of thousands of glowing points reshape itself while it moves.

How to use it

1. Start with one of the six built-in presets: Medusa, Cephalon, Aurelia, Pyrosoma, Siphona or Anemone.
2. Open the parameters panel (on a phone, use the Open parameters button) and drag the sliders. The form changes as you move them.
3. The sliders are in four groups. Morphology sets the overall shape, including the bell and the tentacles. Dynamics covers size, pulse and wave speed. Rotation and Symmetry sets the spin and how many times the form repeats around the centre. Appearance covers opacity, background darkness, point density and the stroke colour.
4. Expand or collapse the groups as you work, and use Reset to Preset to return to the preset you started from.
5. When you like a form, press Save Preset, name it and save. Your presets appear alongside the built-in ones and can be deleted.

Features

• Seventeen sliders and a colour picker, drawn live on a canvas as the animation runs.
• A readout of the current formula as you adjust it.
• Six built-in presets and room for up to 20 of your own.

Questions

What is it based on? A parametric formula first shared by @yuruyurau, which this tool turns into a set of adjustable controls.

Can I download the image? Not from this tool at the moment.
