A large pool of slowly undulating fog is evocative of the cloud tops of Jupiter and Venus as well as of fog forming in the valleys of Mars. Generated by an ultrasonic fog machine, the cool, dense water mist flows like dry ice fog. The top surface is alive with waves and complex convection currents. Side lighting accentuates the patterns. Viewers will be able to run their hands through the fog and alter the currents. When left undisturbed, the fog will slowly churn, constantly changing due to its own internal dynamics.
