Well, not as interesting as your solution, but definitively less mind-boggling
and much more flexible/extendible
====================================================
l = [True]
pr = {True: '*', False: ' '}
for k in range(15):
print ''.join([pr[x] for x in l])
l = [True] + [l[i+1]^l[i] for i in range(len(l)-1)] + [True]
====================================================
more elegant solutions sought!
