Kito Tosetti: Elements

A floating gallery with a glassbottom floor is an appropriate space to see Brazilianborn artist Kito Tosetti’s fluid abstractions. Tosetti explores different digital technologies, titled “Glass,” “DMT,” Fibonacci” and “Red and Yellow,” to create four collections of psychedelic, fractal-like images — or “alternate realities,” as Tosetti calls them. Opens Dec. 10, 5 p.m. to 9 p.m.; runs to Dec. 20 | Nudelman Collection Floating Gallery (Granville Island)
