First step toward Replicators

One of the cooler technologies of Star Trek: The Next Generation is "replicators" - devices capable of producing nearly any food, material, or device from pure energy. In the mythology of Trek, these devices have essentially ended the laws of supply and demand by providing any material item, providing there is enough energy available. For the first time, scientists have taken a first step toward such technology by creating a primitive form of matter out of a beam of light.

It is only a first step, but who knows where it may lead?
