Sixteen creatures, one loop. m = i%16·13 assigns each point to one of sixteen siphonophores — colonial animals that are actually colonies of cloned organisms. Each gets its own phase offset through every term.

The magic exponent. p = d^sin(d²−t+m): the exponent itself swings between −1 and +1 as time passes. Points near the creature stay anchored while outer points get flung outward and recalled — that's the tentacle reach-and-grab you're watching.

The figure-8 current. All sixteen ride a shared Lissajous path — 99·sin(c) across, 99·sin(4c) up/down. A 1:4 frequency ratio traces a figure-8; the phase offset m spaces them along it like beads on an invisible wire.
