they can usually be found in waterparks around the world, surrounded by young kids attempting to destroy the hidden pole that holds it up. well late japanese-american architect isamu noguchi took this family favourite one step further and created an incredible looking set of fountains for the world expo in osaka, japan. the effect is stunning and surreal, the boxes seemingly held in the air by the force of the water.
these were the only photos i could locate on the intertubes. if you know of any others please let me know.
