A virtual connector post (or customized wall module intersection) includes a variable angle connector assembled with a plurality of position retention mechanisms and a corresponding plurality of connector interfaces of corresponding wall modules. The virtual connector post can be varied for virtually any shape or design simply by varying the shape of the variable angle connector(s) used therein. In particular, the variable angle connector can be arbitrarily shaped so that the ultimately joined wall modules form a corresponding, non-standard angle, such as non-right angles between wall modules in a given partition. The variable angle connectors and corresponding position retention mechanisms can be securely fastened between multiple wall modules at any number of arbitrary points along the length of a partition.
