Museum of Contemporary Art, Tokyo

Closes Sept. 28

Someone recently told me they find it hard to think in the Tokyo summer heat. In the cool of the Museum of Contemporary Art, Tokyo's current exhibition, "Parallel Worlds," they won't have to while perusing this light show of high-spirited art. Main artist and curator Hugues Reip leads off the first room with humorous pieces that play on the natural world. His best are works that use light, as in "Eclair 2," a depiction of lightning done in fluorescent tubes; "Flip/Flop," four rectangles with shifting dots; and "Shirei-seirie," a shadow play that riffs on Japanese monsters, a popular summer theme.
