For the Design Studio "Bizarro World" gallery.
In this world, fireflies move around in little tornadoes as a defense mechanism to confuse bats, whose acoustic sensors interpret the formation as a giant deadly cone-fern. The fireflies also leave fluorescent trails in the air in response to nearby crickets, thereby lighting the way for nocturnal predators that feed on crickets.
Move jar around to catch fireflies. Dump jar on ground to release them.
As with the real world, this project works smoother when downloaded.
