The photons ricochet off 25 mirrors arranged in a 5- by 5-foot square and converge in a shaft of light brighter than the sun at high noon. The tightly focused stream crashes into 100 square inches of silicon suspended over mirrors, sending a spray of electrons dancing down a copper wire. A CPU revs and tiny motors whir.
