SensiTile technology allows various materials to react to changes in light intensity and color. Using the same principle that makes fiber optics possible, the embedded light-conducting matrix in a SensiTile material either reconfigures the shadows that fall on it or redirects and scatters any oncoming light. In an environment with ambient light, any movement around the material that casts shadows will produce a set of "ripples" on the material's surface; while in darker environments, any beam of light falling on a SensiTile is redirected to emerge from another part of its surface.
