Unlike the traditional zoo this is place where the animals remain by choice, a zoo without cages. Like a traditional zoo, it is a series of sites where animals and humans interact. However, the interactions at an OOZ site differ from that of a Zoo. Ooz is interactive in that it provides human a set of actions, the animals provide reactions and these couplets add to a collective pool of observations. The human/animal interface has two components: 1) an architecture of reciprocity, i.e. any action you can direct at the animal, they can direct at you and 2) an information architecture of collective observation and interpretation.
