I'm not sure how it works, but this 8-ft by 8-ft clock by artist Miss Moun displays the time by selectively lighting up words in a poem. Three words are always lit, and each word represents either the hour, minute, or second. The piece is entitled "6 Is for Blossom", and you can view more pictures at the link.
