"The wall is made up of thousands of LED lights that were engineered to turn on when water hit them. Anything that is wet, your finger, spray bottle, brush, or water atomizer can be used to “paint” the surface. Artists can draw pictures, abstract shapes and words with a result that is glowing, ephemeral and temporary."
