The Creator of the universe could place a message on the most cosmic of allbillboards, the Cosmic Microwave Background (CMB) sky. It was proposed by Hsu &Zee (2006) to to search for such a message in the CMB angular power spectrum. Iprocess the temperature measurements taken by the Planck and WMAP satellitesand extract the binary bit-stream. I estimate the information content of apotential message in the stream as about 1,000 bits. The universality of themessage may be limited by the observer-dependent location in space and thefinite observation time of order 100 bn years after the big bang. I find nomeaningful message in the actual bit-stream, but include it at the end of themanuscript for the interested reader to scrutinize.
