Math can be so incredible beautiful! You don't believe me? Look at this wonderful art i did today:
Here is the Function which generates this figur:
(x,y,z) = ((x2-y2) * (1-((z2)/(x2 + y2))) , 2xy(1-(z2/(x2+y2))), -2z((x2+y2)*(1/2)))
in my case the iterationsize was 10. You can also try this with higher value, just change the max value!
