The Convolution puzzle is a dissection of a 4x4x4 cube. The goal for this puzzle was to make it serially interlocking with symmetrical patterns on the outside faces. One of the pieces (3rd during disassembly - left-front in bottom photograph) must be rotated slightly during assembly and disassembly. Stewart made 50 from 1980 to 1983. Number 30 in his numbering system.
