Artist installs swings in US subway trains
Artist Hunter Franks has installed swings on subway trains and hopscotch grids in front of ticket kiosks in San Francisco, US. He said, "I couldn’t think of a better place to insert some fun and connection." Some of Franks' other works include a collection of 'first love stories' and a dinner for 500 people eaten at a 500-foot-long table.
