Open Call is an installation that includes two participants at a time, two walkie-talkies, and two sets of 500 questions stored in plastic cases. The project invites participants to step outside their habitual modes of interaction. It creates a temporary space for dialogue based on openness and mutual presence between two individuals who might not otherwise have met. Visitors are guided to converse in a manner that is intimate despite being displaced, as they do not speak face-to-face, leading to an interaction that may actually breed more warmth and dialogue. The conversation is guided by the questions drawn from diverse sources: newspapers, tabloids, chatrooms, schoolbooks, social media, astrology, academic research, personality tests, and Dutch tea-bag messages. When the call ends, participants are left with the anonymous content of their exchange. Open Call facilitates a co-created dialogue that exists only in the moment and belongs solely to the two who shared it.
