What are the most creative methods of activism you have heard of?

What creative methods outside of the box you have heard of? Even new innovative remixes of old ways like flyering, street theater, etc. I think for example the anti-Scientology group “Anonymous” is on the “cutting-edge” of 2.0 Activism to an extent with branding, collective decision, using Web 2.0 extensively, the costumes, videos. Save Darfur had some interesting ideas. The Obama Campaign made extensive use of Web 2.0 but was still the traditional door to door, canvass, phonebank, and GOTV.
