Projection Art, Light Art, laser art, shadows and light. Imagine something like any of these on our Provincial Building, they would even be easy to change at any given time.
These headphones were created by David Storen, using light and shadows, he has also done portraits. Just like the image below, where the pile of stuff in front of the shadow looks unrelated it is that unrelated heap that creates the image on the wall
This one reminds me of the shadow tent I saw at Trout Lake, during the lantern festival. Silhouettes of buildings with windows, people on bicycles, flying through the air, trapeze artists, and 2 people with 2 bright lights each moving them back and forth, making the shadows dance on the screen. Very nice
