The Digimech Clock designed by Duncan Shotton. A video of the clock functioning can be found here. The artist explains that the
numbers are printed on vertical sliders and only reveal themselves when shifted into perfect alignment with the ‘display box’. When not aligned they look like random, alien forms and represent the negative of the number that is required. the sliders are gradually cranked up using motors coupled to intricate mechanics in accurate time. Upon reaching the last number (e.g. the 9th minute) the same motor disengages the ratchet’s ‘stopper’ and the slider then falls to the first number again.
