The Max Planck Institute of Molecular Cell Biology and Genetics has a logo that changes every time it gets used on letterhead or displayed on a web site. The logo system was designed by Michael Schmitz and is based on cellular automata like John Conway's Game of Life. "Parameters [for the logo] are coupled to certain factors: number of employees = density, funding = speed, number of publications = activity. Different logos are being 'bred' and then picked by fitness in relation to the parameters or voted for by the employees." Schmitz's PDF document Evolving Logo is worth a look even if you don't read German. (Anyone want to do a translation? It looks fascinating.) (via bbj)
