Quantum mechanics describes phenomena in the microcosm that seemingly cannot coexist with the laws of the macroscopic world. In 1935, Erwin Schrödinger formulated the scenario of a closed box containing a cat and an unstable atomic nucleus, which has a certain probability of emitting radiation within a certain period of time. Using a Geiger counter, the radiation triggers the release of poisonous gas, which would kill the cat. Schrödinger argues that, if quantum physics were also applicable to macroscopic systems and not only the atomic nucleus, the cat would have to get into a state of superposition. This quantum state would not stop until someone opened the box and checked the cat's condition. The measurement determines if the cat is “dead” or “alive”. Until then, the cat would be alive and dead at the same time. This paradox in modern physics invites artistic experimentation.

In a reversal of the original thought experiment by Erwin Schrödinger, a large cat is sitting on a triangular box staring at the both-and quantum world inside the structure. The box is accessible through a door and can contain up to two participants at a time, while they endure everchanging quantum states as Schrödinger’s Rat, the cat’s uncanny prey. The participant of the interactive sculpture becomes part of an experiment in which they are simultaneously subject and object. As Schrödinger’s Rat, the participant cannot decide the final outcome of the experiment. The quantum state is controlled by the cat as the outside observer. Observation imposes its reality on the objects inside.

The immersive experience design of the sculpture’s inside is the subject of this open call and must fulfill the following artistic criteria, as well as align with the following principles:

• Artistic excellence in media art and immersive experience design

• Aligning with the multiverse theme of Schrödinger’s Rat and capturing the quantum mechanical model described in Schrödinger’s original thought experiment

• Aligning with the Burning Man ethos outlined in the 10 principles

• Creating an interactive space for one or two participants

• Outside sculpture and inside immersive experience have to interact

• Artistic Inquiry: How can reality be determined by observation? How can quantum physics be applied to macroscopic systems? How can something be ‘dead’ and ‘alive’ at the same time?
