Here is the Zome Ball.
You can spin it around.
The following image is a Pickover inspired strange attractor.
xn+1 = sin(yn*b) + c*sin(xn*b)
yn+1 = sin(xn*a) + d*sin(yn*a)
xn+2 = sin(yn+1*b) + c*sin(xn+1*b)*(-1)
yn+2 = sin(xn+1*a) + d*sin(yn+1*a)
As you can see, two symmetrical overlapping attractors are produced.
I'll try to modify the code to make this more interactive. Source
code for this image. A lot of points (a,b,c,d) provide degenerate
images. I haven't figured out why, yet. Perhaps someone will
tell me. Would you like to see more items like this? Send
