With all the planned protesting and civil disobedience, I feel I must contribute an idea. Most of what is going on will not remain after the protest sessions end. People have to go home sometime. But what will make a more lasting statement? That's right folks, Public Art.
As a form of protest, I advocate all of you to compete to see who can make the Biggest, most Grandiose, and most Prominent public art in Portland. Team up - there is strength in numbers.
Art should not permanently alter the area it is placed in (No one wants to be convicted of vandalism). Sidewalk chalk is an ideal medium in my opinion (though the current weather makes chalk a little difficult). A large bucket of 52 big chalk sticks can be had for $5 at Art Media or just about anywhere else. Enormous street murals in major intersections or plazas can be easily made in the dead of night when there is little to no traffic. Other forms of creative display are encouraged as well - installations, performance art, anything you can think of - as long as it is big and public. If you can drape an enormous sign over a prominent billboard, that would be quite impressive, though I should not advocate that, as it could probably get one into a lot of trouble.
On independence day last year my girlfriend and I wrote out the US Bill of Rights on Terry Shrunk Plaza in 6 inch high letters (with a 4 or 5 foot tall title) as a protest to the President's attacks on American liberty. It occupied about 3/4 of the pavement of the plaza. Think above and beyond this scale. Be ambitious. Make the message known - NO WAR!
And of course, post pictures.
