There was a bulletin board in New Orleans about 10 years ago that used the PONTCHIPPI moniker. It was a [FIDO] FIDO/OPUS Network member system, which might explain the fido on the chip inlay. The square root of -1 now must indicate a math-oriented webmaster. Since that can't evaluate to a real number, maybe he was again including a subtle clue to the board's purpose. Google gave no help with the McM's. Since PONTCHIPPI has a registered trademark symbol, it should be possible to research it further.
