Murmuration — starling flocking simulation

A starling-style flock moves as one mass against a sunset sky and tree silhouettes. Cursor attracts and disturbs the flock.

• Fish pondA school of goldfish in a dark pond; they flee from the cursor while light caustics ripple the surface.
• FirefliesFireflies wander a dark grass field; cursor is a lantern that pulls them in. Click flares the lantern and scatters the swarm.
• Slime moldPhysarum agents sense, turn, step, deposit; the trail map diffuses and decays each frame. Cursor deposits attractors; click drops a burst.
