Rossler

Rössler Attractor — Proposed by Otto Rössler in 1976 as a simpler system that produces chaotic behavior. Unlike the Lorenz system's two-lobed shape, the Rössler attractor has a single folded-band structure with an outward spiral that occasionally makes a large excursion in the z-direction.

dx/dt = −(y + z)
dy/dt = x + ay
dz/dt = b + z(x − c)

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.
