What is it? I've seen similar things in discrete Volterra-Lotka Julia fractals, but I'm guessing similar patterns can be generated in a variety of systems.

It's a weird Julia set variant, colored based on escape time.

Iteration formula
Let z(-1) = z(0) = standardized pixel coordinates, often called "c"
For n = 1, 2, . . .
   Define s, t, u, and v by: z(n - 1) = complex(s, t) and z(n - 2) = complex(u, v)
   Let z(n) = complex(1.5*s^2 - 1.5*t^2 + 0.3, s*v + t*u + 0.6)

Zoom region
Real axis: -0.35 to 0.29
Imaginary axis: 0.20 to 0.70
