The three dimensional, three-sided clock face appears as if looking into the corner of an open box. Along the sides, snakes a continuous track made up of shelves and ramps. Steel balls roll on the track and act as counters for hours, ten minutes, minutes, ten seconds and seconds. The balls enter and
exit the track via doorways.
Every second, a ball rolls onto the track and stops by the others displaying the seconds. When the tenth ball arrives, the first ball follows the track to the ten seconds display, and the other nine exit through a doorway. When there are six balls in the ten seconds display, the first continues to the queue of minute balls and the others exit. This continues through to an hour display.
All exiting balls are returned to the entrance doorway by gravity. Since one side’s horizontal track is another’s vertical, the balls must be held and moved on the track by magnets (linear or on a belt), hidden in the track. Thus, the balls tell time while seemingly rolling on impossible planes.

best yet - love it. however there really ought to be people lolling out of the windows and sitting on the stairs holding their heads in despair. |

Just don't let Bowie get in there. He'd pick up three balls, start spinning them about in his hand and mess the whole thing up. |

My morning must be looking up, another amazingly beautiful clock to marvel at and a labyrinth annotation. |

Allright who fishboned this? Least you could do is give a reason. + |

i like this, a clock that looks like an escher drawing, with marbles that cling underneath with magnets.
we had a steel ball clock about 20 years ago.
it was funny, my sister had a slumber party once, and the noise that one am made (when all the balls rolled down and rattled) scared all the girls. |

Looking closely, if the ramp levels were spaced out a little more so that the entire spiral actually runs downhill, the only part of this clock that actually needs magnet assist is the right side, where the marbles roll on a side-plane. |

It'd be real fun watching the rollover from 12:59:59 to 1:00. |

Very fine. The collison of Escher and FJ was inevitable, but never did I think it would be this satisfying. |

[farmer] I swear you have hung your picture up the wrong way. I have to look at it in the manner of a :) |

You sort of have to wobble your noggin to take it all in. |

Fantastic idea. Great illustration too. Now can you figure a way to make the third plane work too? (A third plane of reference) |
|
| |
I couldn't get my head around it until I did the [po] trick. I'm waiting for the magical day when [FJ] finds out that his neighbour is an insane horologist with too much time on his hands. |
