I take the code from Gustavo Niemeyer and modify it a bit.



import e32

from appuifw import *



app.screen = 'full'

app.body = canvas = Canvas()

width, height = canvas.size



xaxis = width/2

yaxis = height/1.5

scale = 60

iterations = 25



for y in range(height):

  for x in range(width):

    magnitude = 0

    z = 0+0j

    c = complex(float(y-yaxis)/scale, float(x-xaxis)/scale)

    for i in range(iterations):

      z = z**2+c

      if abs(z) > 2:

        v = 765*i/iterations

        if v > 510:

          color = (255, 255, v%255)

        elif v > 255:

          color = (255, v%255, 0)

        else:

          color = (v%255, 0, 0)

        break

    else:

      color = (0, 0, 0)

    canvas.point((x, y), color)

  e32.ao_yield()

 

lock = e32.Ao_lock()

app.exit_key_handler = lock.signal

lock.wait()
