New Circadia (adventures in mental spelunking) was an installation at the University of Toronto's John H. Daniels Faculty of Architecture, Landscape, and Design.

[1] The installation, which opened on November 7, 2019 and ran through April 2020, was the first exhibition to take place at the Faculty’s Architecture and Design Gallery, located in the lower level of 1 Spadina Crescent.

[3] Designed and curated by Daniels Faculty Dean Richard M. Sommer with Natalie Fizer and Emily Stephenson from the New York based studio Pillow Culture, the intent of the installation was to create a space designed specifically for visitors to disconnect from technology, and re-connect with their circadian rhythm.

[3] Inspired by Nathaniel Kleitman’s 1938 Mammoth Cave Experiment which investigated sleep and wakefulness,[4] it presented an immersive, cave-like environment.

[8] The loungers included built-in speakers that emitted soft humming and wave-like noises created by an assistant professor at the Daniels Faculty, Mitchell Akiyama.
