This image created with the
spectrum intercept algorithm
is based on the dynamical system characterized by the expression,
where θ'' is the second derivative of θ with respect to time.
The parameter values are b=3.33, μ=0.0133.
This image differs from the Rainbow Wave image by b=3.33 instead of 1.96, μ=0.04 rather than 0.133 and a different domain.
