“Shadow Up®︎” is an interactive installation where shadows—not light shows or projection mapping—take center stage.
Using our proprietary StereoLight® system*, the work transforms any environment into a vibrant space where light and shadow leap into the air. It creates an immersive world of dynamic, three-dimensional imagery with limitless resolution, rendered in real time—entirely without CG.
The result is a one-of-a-kind analog experience, full of surprise and wonder that can only be felt in the moment.
