Jigsaw pieces with binary coded tabs which result in values that match up with the numbers of a 4th order diabolic magic square (of sum 30). This design could be made available in almost any size or colour scheme. At the moment the colours for the numbered blocks correspond to a slight variation on the old RGB (+ lightness) bit coding used on some older computers. Other colours, stylings, sizes and orientations are available on request and you can even ask for a combination of several designs together.
