Privacy issues can be difficult for end-users to understand and are therefore a key concern for information-sharing systems. This paper describes a deployment of fifteen Bluetooth-beacon-enabled 'creatures' spread across London's Queen Elizabeth Olympic Park, which initiate conversations on mobile phones in their vicinity via push notifications. Playing on the common assumption that neutral public settings promote anonymity, users' willingness to converse with personified chatbots is used as a proxy for understanding their inclination to share personal and potentially disclosing information. Each creature is linked to a conversational agent that asks for users' memories and their responses are then shared with other creatures in the network. This paper presents the design of an interactive device used to test users' awareness of how their information propagates to others.
