TWELV brings art, fashion, and technology together in a series of horological systems and devices in which the function served by a traditional clock hand or numerical digit is served through the use of color, shape, and other indicators. Below are images from a TWELV moonphase clock (requires Flash) built by artist Christopher Chalsma, in which the background color indicates the current hour of the day and the shape of the moon indicates the current minute of the hour.

To illustrate in more detail the function of the moonphase as a minute indicator, here are two images showing how the moon in the Chalsma clock appears at six minutes before the hour and six minutes after the hour.
