The Quantum Parallelograph is an exploratory project by Patrick Stevenson Keating examining the scientific and philosophical ideas surrounding the theory of quantum physics and multiple universes. The device delves into the multiverse, and allows users to glimpse into their "parallel lives" - to observe their alternate realities. The device uses online sources to find the "parallel lives" of users, and prints out a short statement about their "simultaneous" life in a parallel world. The dial and knob you see in the photos are used in selecting the intensity level of the search. The button sends a single photon through the glass tube and performs Young’s Double Slit experiment. At this point the readings are taken for the particular person’s parallel lives, and printed out from the slot.
