Leo Villareal (American, b. 1967) creates abstract light works using custom-written computer code to control arrays of LEDs, producing sequences that shift and evolve without a predetermined outcome.,His practice grew out of a functional idea at Burning Man in 1997, where he rigged a strobe-light array above his tent to find it after dark, a device that became a prototype for his later work connecting software and light.
He studied sculpture at Yale University, graduating in 1990, and completed a graduate degree in New York University's Interactive Telecommunications Program in 1994. Villareal presented his first fully realized LED sculpture, Hexad, in 2002. The following year he produced his first large-scale architectural work, Supercluster, for the group exhibition “Signatures of the Invisible” at P.S. 1 Contemporary Art Center in New York, made in collaboration with CERN, the European Organization for Nuclear Research.He has been represented by Pace Gallery since 2016.
In 2013 he unveiled The Bay Lights, a light installation of 25,000 LEDs strung across the San Francisco–Oakland Bay Bridge, which was made permanent in 2016.After a three-year absence, the work returned to the bridge in 2026 following $11 million in fundraising.His Illuminated River project extended this practice to London, adding LED lighting to bridges of the River Thames in stages between 2019 and 2021.
Villareal extended this code-based light practice into blockchain-based work with Cosmic Reef, released on the platform Art Blocks in 2022.,Its underlying script, at 121,138 characters, was the longest of any Art Blocks project at the time.He followed it with Cosmic Bloom, an NFT collection presented with Outland in 2022.His algorithmic, LED-driven approach to light has been cited as an influence on younger generative artists, including Andy Duboc.
His Particle Field (Triptych) was shown in the exhibition “Hyper Digital Forces” at Borusan Contemporary, Istanbul, in 2023.In 2026 Pace exhibited works from his Golden Game series at Frieze New York.That year his work was also included in “Run the Code”, an exhibition on data- and algorithm-driven art at the Blanton Museum of Art.Villareal's work is held in the collections of the Museum of Modern Art, the National Gallery of Art, and the Brooklyn Museum, among others.
