Weather Machine II is an interactive installation developed by Nathen Street for the Smithsonian Institution Travelling Exhibition Service. Inspired by the natural water cycle, the machine captures the essence of evaporation, precipitation and flow.

When someone grips monitor paddles, their heartbeat powers the different phases of the water cycle: tornado (evaporation), precipitation (water dripping into collection bowls) and flow process (water moving through and reused in a closed system).

I wrote software that measured heartrates, actuated pumps, lighting and a smoke machine via relays and a DMX controller.

Weather Machine II is part of the Smithsonian’s ‘H20 Today’ exhibition. Tour dates and details can be found here.
