To Argentinian-French artist Julio Le Parc, the individual’s experience of his work is everything. From inventing games that could be played on the street to constructing installations of moving lights, Le Parc has experimented with ways to draw in his audience and heighten their perceptions of the world around them. Here, at Perrotin Gallery, hanging aluminum shapes reflect the gallery and visitors, bringing both into the experience of the sculpture. (On view on the Lower East Side through Dec 23rd. Masks and social distancing are required).
