*923 Empty Rooms* is an artwork about simulation and the history of visual representation and abstraction. Each room is a space to explore. Each of the 923 unique rooms contains a simulated still life, an arrangement of forms. There are six primary forms, each linked to a city: Sun (Tokyo), Shard (Berlin), Cargo (London), Hive (New York), Pyramid (CDMX), and Moon (Los Angeles). A series of rooms will be minted over the course of a simultaneous, six-day exhibition at galleries in each city. There are 923 rooms in total to iterate through every possible combination of the six shapes: 1 form = 6 unique combinations 2 forms = 21 unique combinations 3 forms = 56 unique combinations 4 forms = 126 unique combinations 5 forms = 252 unique combinations 6 forms = 462 unique combinations *923 Empty Rooms* is an evolution of *An Empty Room*, commissioned by the Los Angeles County Museum of Art (LACMA) for the Coded: Art Enters the Computer Age, 1952–1982 exhibition. *An Empty Room* was installed at LACMA from 9 April to 2 July 2023.
