Joanne and I went to see the new show of works by Gabriel Orozco at the Serpentine Gallery. He’s most famous for a human skull, inked over with a pattern of criss-crossing diamonds. It’s beautiful, it’s about mortality, geometry, and it’s about imposing our will upon the world (and vice versa). Orozco is a painter, a photographer, a sculptor, zigzagging across the lines between geometry (his cut-up airline-ticket collages), formal beauty (the gorgeous manipulated photo of sun-dappled leaves opening the show) and the conceptual (hanging drier-lint).
