The clf call seems quite wrong:
it flashes horribly and I get good
behavior without it (once I add
a call to sleep). What am I
missing?

PS The following almost works (i.e., works,
but then exits wi
loop through the data and call clf():
from pylab import *
from numpy import *
ion()
hold(False)
frame1 = zeros((200, 200))
frame1[20:40, 20:40] = 255
frame2 = zeros((200, 200))
frame2[20:40, 30:50] = 255
frame3 = zeros((200, 200))
frame3[20:40, 40:60] = 255
frame4 = zeros((200, 200))
frame4[2
