The fish symbolism below was popular with left activist newsletters during the 1980s, the bottom one actually being based upon a children’s book with a title I don’t remember about a pariah black fish among red fish eventually serving as an eye in the revolutionary formation.

The image comes from this American Friends Service Committee site – always loved the Quakers.

Well, some chess geek came up with an even better image. It comes from imageshack, and I’ve found it on various sites, but I can’t find an attribution.
