Fireflies combines a physical interface, in the form of a glass jar with a crank handle and a digital environment. Inside of the glass jar are 21 small, yellow LED lights to represent fireflies. As the user cranks the handle on the top of the jar, the LED lights inside of the jar will react to the interaction. Simultaneously, the digital environment shown on a screen has digital fireflies being generated within the environment; also as a reaction to turning the crank. Depending on the number of times as user turns the crank, the more fireflies will appear on the screen, and the longer the LED’s within the jar with dancbnnvve.
