a prediction: To validate the trust of those who believe, as well as to reconcile the doubt of others, I have gone to great lengths to plan the following display of communication: Monday, July 18 East Rutherford, New Jersey Approximately 10:30pm Flashing white lights. There is an enigma. Trust. On the night of 18 July 1994, patterns in the lights on the front of the stage at the Pink Floyd concert in East Rutherford momentarily spelled out the words ENIGMA PUBLIUS. In September 1996, the Penet remailer service was shut down by its creator over legal threats posed to the guaranteed anonymity of its users. As a consequence, contact to the newsgroup through the associated Publius account ceased. Subsequent Publius-style posts from other addresses have led to differing opinions over the status of the enigma and whether or not it has ever been solved. Official statements During a 2002 webchat, guitarist David Gilmour said the puzzle was "some silly record company thing that they thought up to puzzle people with". In April 2005, during a book signing of his biographical work Inside Out: A Personal History of Pink Floyd, drummer Nick Mason affirmed that it had been instigated by the record company: The comments made by Mason corroborate parts of a previous interview by Sean Heisler with Marc Brickman, Pink Floyd's lighting and production designer and the man apparently responsible for putting the "ENIGMA PUBLIUS" message in the lights at the New Jersey concert. Douglas Adams, who was credited with having given the album its title, categorically denied any knowledge or involvement and dismissed the idea of the band members being responsible: Uncle Custard The Pink Floyd magazine Brain Damage had a Q&A section reserved for a correspondent known only as "Uncle Custard". The name (phonetically similar to "Uncool Car Stud") was created by Glen Povey, apparently an allusion to Nick Mason's passion for auto racing. Issue No.34 of the magazine contains the following: Although the answers given by Uncle Custard over the years have all been written by several different people affiliated with the magazine, this particular response has been attributed to former editor and final publisher of the printed version of Brain Damage Jeff Jensen. The accuracy of the content of this answer and under what authority (if any) Jensen had to produce it remains unclear. In the media Possible references to the Publius Enigma can be found
