As another note, the NY Times Lens blog surfaced a new picture of Tank Man. The video (below), is mindblowing. I toyed with an entry tracing some of the various ways that Tank Man has gone viral, but the only entertaining and juicy bit I came across was a "Tank Man Tango" (described as "a memorial of dancing bodies") that went on this year in Australia to commemorate events.
As child of the diaspora here, I primarily remember the set of events as a series of panicked faxes. The onset of the fax machine had been crucial in helping organize the protests, and getting a record of what had happened out of the country and out of sight of censors. (By one account, guards had been posted by all publicly available fax machines the morning of June 5.) I've yet to see [though I certainly haven't dug deeply] a good account that captures this dynamic though - there is not so much action, of course, in the clicking, whirring noises of a fax transmission. But to that nerve-wracking noise, many abroad received their handwritten notices sometime twenty years ago, far before the news stories broke, and anti-climactically felt the tide turn.
