a quick python gist for generating fractals using compositions of sin() and another function

sin_frac.py

from PyQt4.QtGui import QApplication
from pylab import *
ion()

ny = 600
r = 1.25
nx = ny*r
iters = 10
grid = pi*2/3

ay = flipud(linspace(-grid, grid, ny))
ax = linspace(-grid*r, grid*r, nx)
z = complex128(tile(ax,(ny,1)) + transpose(tile(ay, (nx,1))*1j))

u = exp(2*pi*1j*rand(1))

subplot(121)
im_abs = imshow(abs(z))
subplot(122)
im_angle = imshow(angle(z))

for n in range(iters):

    z = sin(u*z)
    
    im_abs.set_data(abs(z))
    im_angle.set_data(angle(z))
    title(n+1)
    draw()
    QApplication.processEvents()

print("done")
