The  béton  Garden of  paradis   signe . Blink blink blink goes the radium metal embedded in the  béton . Other trace elements, which emit odors for millions of years in the same way that radioactive materials emit  radio  without stopping (transmissions moving from star to star, never quite loud enough to hear, never quite soft enough to block) are embedded under every other  lettre . Plus, the whole thing is lit at  nuit  (or would be, if  nuit  ever came... parts of the general machinery are broken).
