    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

Feigenbaum Flower. Homage to Mitchell Feigenbaum (1944-2019). He demonstrated the universal character of dynamical non-linear systems, which has made possible the systematic study of chaos. In 1975, using the small HP-65 calculator, he discovered that the ratio of successive distances between bifurcation events tends to a constant δ ≈ 4.66920... This "ratio of convergence" of period-doubling bifurcations is now known as the first Feigenbaum constant. #bifurcation #attractor #fractal #chaos #math

Great!! This is the famous Clifford Pickover Attractor!! It appears in his book Chaos in Wonderland (by the way, I am cited in this book as a fractal poet). Many beautiful variations of this Attractor can be made by changing only 4 parameters. #fractal
u/katkip

I don't understand
u/SMON

I wonder what's going on here. Is there any way to understand this? :)
u/thorbear

Didnt know about Clifford. Used the formulae on P.Bourkes page: http://paulbourke.net/fractals/peterdejong/
u/thorbear

He also has one on the Clifford attractor under /fractals/clifford
u/robbyg

Well done with the #attractor -- I didn't get color in mine: https://www.dwitter.net/d/8503
