The era of the public display is upon us. In the past year, two public display projects have been deployed inside of SI; Paul Resnick's "Thank you display" and more recently, Josh Palay's MichiPosters. In this talk, I will provide an overview of existing public display projects, introduce a growing genre of audience aware
public displays, and discuss two specific public display deployments in Design Lab One and Nokia Research Palo Alto. The talk will conclude with a discussion of how Prospero can make it easy to "play" and "explore" the audience aware-display design space.
