Sprott A

Sprott A (Nosé–Hoover oscillator) — the first of J. C. Sprott's 1994 systems and the only conservative one: rather than settling onto a strange attractor it fills a chaotic sea.

dx/dt = y
dy/dt = −x + yz
dz/dt = 1 − y²

It opens running, on the model selector, with its own knobs. Rotate it by dragging, zoom with the wheel, and turn the parameters to see what the figure does when the system changes.
