The recent OccupyIntegral! article has inspired some good conversations about the nature of protest, activism, and taking concrete steps to change something about your community (be it global or local) that you think is important.
The video below reports on a unique and intriguing example of grassroots activism (man, how did the word grassroots get to feel so cheesy. I don't know how that happened and can't think of a replacement at the moment - bottom-up, maybe? Annnyyyhow...). It strikes me as pretty darn savvy at using boots on the ground, street art, and the networked relationships we're all so linked into.
(If you're short on time the last 10mins will give you an idea of what's up).
