  We argue that the cosmic microwave background (CMB) provides a stupendous
opportunity for the Creator of universe our (assuming one exists) to have sent
a message to its occupants, using known physics. Our work does not support the
Intelligent Design movement in any way whatsoever, but asks, and attempts to
answer, the entirely scientific question of what the medium and message might
be IF there was actually a message. The medium for the message is unique. We
elaborate on this observation, noting that it requires only careful adjustment
of the fundamental Lagrangian, but no direct intervention in the subsequent
evolution of the universe.
