Toy koi

LIVE STATE

Shared stage / live cameras0.0 s

One scene. The same poses, seen up close.

00 / Stage

All visible letters and the koi. The ring tracks our minnow.

01 / Koi

The same heading, body curve, and swimming phase.

02 / Minnow

One actual letter, enlarged. Its fins follow its speed.

03 / Fins

Oversized fins lag behind turns, then settle.

04 / Tail

The flowing fan bends with the stroke and turn.

05 / School

The same minnow’s neighbors. Arrows show actual velocity.

All cameras share the stage clock. Pause motion freezes every view.
