Word Clock is a free typographic screensaver for Mac OS X and Windows. It displays a fixed list of all numbers and words sufficient to express any possible date and time as a sentence. Word Clock displays time by highlighting appropriate words as each second passes.

There are two display modes; Linear (my favoured) and Rotary referencing traditional analogue clocks. Yo can customise typeface, colours language, text type, case and more.

The original Word Clock was written in Mac OS X native Cocoa language using the Apple Xcode. The current version is written in Flash ActionScript 3 for the screensaver and Flex for the configuration interface to be cross platform. This is published for Windows using the free Instant Storm and for Mac OS X some custom open-source Cocoa code.

Word Clock was created by Simon Heyes, a graphic designer and programmer living in London. He is also a Creative Director at tonic.
