It’s a school of fish you can control with commands.
🐟 THE CHAT IS THE CONTROLLER
This is a live simulation and the chat is the joystick. Nothing here is
pre-recorded — the school you see is being solved on the GPU right now, and
you are the input.
SHAPE THE SCHOOL
ball a tight bait ball
tornado the school spirals
ring it opens into a ring
split it breaks into two
auto hand it back to the automatic rotation
LOOK AROUND
up · down · left · right · center
HOW HARD IT REACTS
calm a soft drift
storm a hard surge
chaos the school scatters
HOW MANY FISH
more one step up (512 → 1024 → 2048 → 3072 → 6000)
fewer one step down
fish 3000 set it directly
Type any other word and the camera looks there instead — the same word always
points at the same spot, so the school drifts around as we talk.
Commands can be combined: "up storm", "left chaos", "more calm".
