July 2024. Artist-led public activations at Brooklyn Bridge Park invite encounters and discourse about the monumental stone circle HALO, geolocated in extended reality 50m / 165ft above the East River. Presented in collaboration with the Saas-Fee Summer Institute of Art NYC 2024, artists, writers, coders and technologists meet to engage with this ancient stone rune as it reframes an iconic skyline, stimulating the imaginary and connecting people through digital fluidity. Drawing from ancient, natural and computational worlds, HALO brings into focus a cultural continuum – past, present, and future – shaped by capital and colonisation in the city that never sleeps.
