The Asian financial hub’s burgeoning art scene has welcomed a crop of avant-garde galleries. New-media artist Teddy Lo opened Input/Output, with tech-savvy installations such as a light display that channels data from the Hang Seng Index and New York Stock Exchange. On view now at Mischmasch Gallery is “Covert,” a mix of canvases and digital works by Indonesian painter Fhung Lie. This month, street-art champion No Borders Contemporary Art is showing “Scratch Game,” Alaskan Gretchen Sagan’s prints made using copperplate etching and drypoint techniques.
