I was co-lead on a project at an immersive art festival in a hotel; we were inspired by the secret half-floor in Being John Malcovich and took advantage of the fact that the hotel, like many, did not have a 13th floor. We created a faithful replica of a hotel elevator with a functional call button, sliding doors, lighting and music. The elevator car was on an indetectably moving platform that seemed to actually take you to the 13th floor. The elevator was a portal that led to a plane of existence that existed everywhere and nowhere. Within the space, scientists set up an illicit lab where they performed tests to pair "stem souls" with participants, assigning them short-term duties, and then recording their experience upon return. The tests allow people to consider the mutability of identity, while the assignments gently encouraged them to try on new identities through their interactions with others.
