River of Time is a permanent installation created for 21c Museum Hotel in Oklahoma City, in an historical Ford Model T production building. The installation uses conveyor belts whose top surfaces are replaced with semi-transparent colored sheets of acrylic, to create moving panels that flow along the conveyor paths like an animated river. The ‘river’ flows up and over the center of the installation like a waterfall. Behind the waterfall is a large clock that shows the current time through LED lights that shine through the panels of acrylic as they pass in front. The conveyor belts provide a material link to the building’s past history as an assembly line while creating a dynamic visual installation that displays the current time. The installation mixes digital technology and mechanical components to create an dynamic sculpture of a flowing river in a reference to the past, present, and future.
