The present invention is directed to apparatus and method for measuring the spectral characteristics of an object surface. Although ideally suited to the Digital Body Development System, the method is applicable to any problem solving environment involving iterative simulations. A look-up table may be generated to include information related to one or more of a source address, a destination address, a length of the packet and a medium access control address. Separately encrypted record elements may be aggregated as an information polymer. The side wall panels engage the bottom wall along their outer edges, and cage a screen between the side wall panels and the end flaps.
