Programmable matter

Programmable matter is any bulk substance whose physical properties can be adjusted in real time through the application of light, voltage, electric or magnetic fields, etc.
Primitive forms may allow only limited adjustment of one or two traits (e.g., the "photodarkening" or "photochromic" materials found in light-sensitive sunglasses), but there are theoretical forms which, using known principles of electronics, should be capable of emulating a broad range of naturally occurring materials, or of exhibiting unnatural properties which can not be produced by other means.
