the bell squeezes fast and refills slow, with a little overshoot. the tentacles just follow.

every number is bell-relative, so a jelly you make can be dropped into any water at any size.

ten real ones and five visitors. tap a real one and it swims into the studio, ready for a witch hat ♡︎

✦ real ones · the ocean made these first, the maker just squints at them
○ rocuronium's jellies · visitors, not residents: tap one and it swims over to the tank. they keep you company in rocuronium, kageroumado's app that lets an ai use your mac without ever taking your cursor

not lookalikes: rocuronium's own swift renderer, ported line for line. in the tank you can switch what they're doing: idle, thinking, acting, or needing you. touch the studio and they swim home ♡︎

how it swims PHYSICS.TXT

elysia@pink:~/medusarium $ cat physics.txt

one contraction curve drives everything.
the first 26% of a beat is a fast squeeze (a cubic ease),
the rest a slow refill with a little overshoot.

the tentacles are never steered. each point remembers
where the bell was a moment ago, so they lag and trail
on their own. their sway scales with the bell's width,
so a skinny jelly's strands hang under it instead of flailing.
the oral arms wave on a separate clock.

glows are radial gradients, never a blur.
in dark water they add light, in the lagoon they tint.

elysia@pink:~/medusarium $

the same formulas swim in piru's jellyfish skin.

how many? COMBOS.CALC
POSSIBLE JELLIES, BEFORE COLOURS

every choice multiplies, so the number of switches matters more than the length of any one list. the count is read off the studio's own controls, so a new hat makes it bigger by itself. add 7 colour pickers and 20 smooth sliders on top and it stops being a number.
