Los Angeles’s Museum of Contemporary Art has a new young fan of its exhibits, although, truth be told, he was built for the purpose. ‘Charlie’ is “an unassuming robot-child with a sweet disposition, inquisitive eyes and a blue tricycle slung low to the ground… Stand and peruse the webs of multicolored and metallic paints in Jackson Pollock’s august 1949 drip-painting, ‘No. 1,’ and the little android with the prominent nose and the permanent grin might well pedal up silently behind you to join the fun. Then, with a twist of his head and a roll of his eyes he’s off, riding into another gallery to check out what might be going on.”
