Evacuating St. Mark's Square

One of the fun things we're working on with Redfish is an autonomous agent model for the evacuation of Saint Mark's square in case of an emergency. The current version is a a very early stage, but it already looks cool. Unfortunately, Venice has been named as a possible terrorist target, plus we've had a major fire in the main theater (the Fenice Theater) in 1996, so this is not as far-fetched as it seems. The full blown project should be sponsored by the local "protezione civile", which is the Italian version of FEMA (Federal Emergency Management Agency) in the US.
