"logic gate matrices" (a.k.a. lgm), developed by brian mcconnell, describes a universal virtual machine that is constructed by connecting coordinates in an n-dimensional space via mathematics and logic operations, for example: (1,0,0) <-- (or (0,0,1) (0,0,2)). using this method, one may describe an arbitrarily complex computing substrate as well as the instructions to be executed on it.
