Carl Bunin is founder of PeaceButtons.info, and he's provided over 110,000 peace buttons to the world (plus lots of other stuff) and he provides a "This Week in Peace & Social Justice" email newsletter, mapping out the movements and actions that have produced remarkable changes in the last century. Formerly on the front of demonstrations, teach-ins, and the like, Carl now does his bit for the peace movement from a wheelchair, due to MS, but it's hardly slowed him down at all.
