Researchers at Cambridge University have discovered the means to draw and erase circuits on the fly. While the process is not perfect--the circuit board has to be kept extremely cold--it promises to drastically speed up prototyping new kinds of circuit designs, which should in turn help lower the cost of chips from a design point of view.
