This contains the code of the sign I used at the West Coast Port Shutdown in Oakland. Here are some pictures: 1 (mirror 1), 2 (mirror 2), 3 (mirror 3).

The poster contained this code :

#!/usr/bin/python
from UCB import occupyCal
from Oakland import Port

for member in OccupyCal:
    member.marchTo(Port)

However, folks on Reddit (rightfully) criticized it for not being PEP-8 compliant.
