What can you do in one second? Listening to the musical/sonic concoctions of sound designers, composers, musicians, piano tuners, and the odd stand-up comic faced with the time restriction, a lot. Asked to "create digital music" in honor of the leap second added to correct atomic clocks New Year's Eve, you responded with an astounding array of miniature compositions.

They also prove that the 23 seconds added to our clocks since the early 70s to account for slowing Earth rotation are no small matter.
