It's an embedded computer with an LCD display screen, which plays a perpetual game of Pong, with one round per minute. The right-hand side wins once a minute, except on the hour, when the left-hand side wins (and the right's score is reset); hence, the score displays the current time. Clocks go on sale next year, though there will be a downloadable screensaver soon.
In a sense, this seems to be the computer-age equivalent of those mechanical clocks from centuries past, in which tiny figures promenaded around illustrating the time of day.
(I wonder what it's implemented on. If the device contains, say, a Mac mini or an entire Linux system and X server, it would seem somewhat decadent.)
