This clock has iron fillings in the face. electromagnets are placed so that they can produce any number (think normal digital clock). When it is on, the fillings are attracted to the numbers, forming the correct time. The electromagnets are behind a highly polished non-magnetic metal surface to provide
the contrast with which you use to discern the shape of the iron fillings.

Needs a vibrator to make sure that the filings don't lump together and clog everything. |

The fillings are sealed of from the rest of the clock. |

charming, well done Mr/Ms [Fox]. |

I see a problem with the iron filings falling down to the bottom of the face. The magnets would have trouble in picking them back up. What is your solution to this? I'm sorry, I cannot think of anything. |

The electromagnets would only have to raise the fillings an inch or two. The electromagnets wouldn't have to be that powerful. |
