The Pudding is a unique website that you should regularly visit (after your hourly check-ins at Neatorama, of course). There's fresh and novel content that informs and entertains readers in clever ways.
This clock, for example, plays music that varies with the time. At 9:13 in the morning, it plays 9:13, a song by the metal band No Murder No Moustache. The song refers to the 1966 Aberfan mining disaster that killed 144 people, most of them children.
It is a work in progress. Some times, such as 9:26, appear and no song titles. Perhaps some enterprising musicians might fill these gaps.
