“Immaterial/Re-material,” an ambitious group exhibition “tracing the history, present, and future of computing art” opens at the UCCA Center for Contemporary Art in Beijing. Surveying the work of 30 artists, active from the 1960s through present day, the Jerome Neutres curated show features a blend of pioneers (Harold Cohen, Vera Molnar, Frieder Nake) and contemporary voices (Memo Akten, Quayola, Wang Yuyang).
