Watercolor Walls

"Watercolor Walls" mixes basic tech tools and audience participation to give new life to your stodgy old silhouette.

Mix infrared light, a camera, and open-source software and you get "Watercolor Walls," a cool interactive art installation that visualizes how light bends to create your silhouette.

When your silhouette comes in contact with one of the colors on the palette, it would change color, and bring that new color down into the rest of the screen. That new color would then interact with the differently colored silhouettes of others. That gives participants a unique ability to control both the on-screen colors and flow of the silhouettes.
