A system and method for decorative elements having multiple visual appearances. The decorative elements may present different colors and/or other visual appearance characteristics and yet function as a durable construction material, like a traditional brick, tile or shingle. The decorative elements may receive a mechanical operation that permanently physically alters the decorative element, such as a cutting, sawing, drilling or molding operation, while the decorative element is functional to provide a controllable visual appearance both before and after the physical alteration. The decorative elements may be autonomous in that power needed to change visual appearance states can be gathered by an integrated energy harvesting device, such as a solar cell. A color chip system may be used to select decorative element features. |
