Computer graphics, reminiscent of this chaotic attractor, were common in his early works.

My guess is that it's probably a chaotic attractor.

When increasing r or the injection current, the two wings of the buttery chaotic attractor grow, hence making the jumps between the two wings easier and therefore reducing the dwell time.

An easy way to visualize a chaotic attractor is to start with a point in the basin of attraction of the attractor, and then simply plot its subsequent orbit.

The Lorenz attractor displays chaotic behavior.
From the en.wikipedia.org
For a certain set of parameters the system exhibits chaotic behavior and forms what is called a strange attractor.

The cases of most interest arise when the chaotic behaviour takes place on an attractor, since then a large set of initial conditions will lead to orbits that converge to this chaotic region.
From the en.wikipedia.org
In contrast, for chaotic processes, a larger correlation exists between points as the system is driven by a low-dimensional attractor, and order can be found in the random-like dynamic.

The Lorenz attractor, named for Edward N. Lorenz, is a 3-dimensional structure corresponding to the long-term behavior of a chaotic flow, noted for its butterfly shape.
