This large, slowly gyrating mobile could embellish the ceiling of a theater lobby or an airport terminal while displaying the time. Its seemingly random movements are not be caused by drafts but are exactly choreographed and executed.
The mobile is made up of five tiers of horizontal beams linked
by non-twisting cables. At the bottom, on the same level are 32 thin, two-sided, monochrome, display panels that can display any number, a colon or just the background color. Their apparently arbitrary progress is precisely steered by electric motors at the ends of each beam, turning the cable that bears the next beam or a panel.
Every 30 seconds a group of four or five panels congregate in a line somewhere within the mobile, and those panels display the time in digits. As these panels leisurely split apart, with fading characters, another group is gathering at another point.

Each tier is a beam suspended by a cable, and it steers two cables that support beams or panels under it. By controlling the total, pre-programmed turning of all the cables, one decides the two dimensional movement and placement of the panels. It looks like a mobile changing haphazardly but is a clockwork composing its clock face at different places. Capisce? |

Does this work somewhat like arrows? |

Come on - time flies like an arrow. |

Fantastic concept, but - non-twisting cable? That'll be a rod then (with or without tiger). |
|
|
Yet another totally brilliant rocking concept, Farmer... croissant for the title alone. |
|

bris, wait another 30 seconds for the arms to come around again, and you'll catch it... |

I already need a little one of those, for the den. Very nice, [FarmerJohn].
You should encase it, so people can't disrupt it by throwing things (wasn't me), or get it tangled with helium balloons. You may need a separate little "AM-PM" panel. If the motors are computer-controlled, corrections are easy (like after power failures), and doing Daylight Saving Time.
I'm probably gonna miss my flight, watching this thing, but somehow I don't care. |

Thats quite a complex time piece there. I can't decide which would be more beautiful the Kaleidoklock or this. |

It occurred to me this morning that the inactive panels in this clock might be visible from other angles. This led me to speculate whether you could design it so that depending on where you stood relative to the clock, it would show you the time in different time zones. |

Perhapse..
You could put electro-magnets and sensors in each of the panels so that when five get
near each other they pull together, figure out if their #1 or 2 et cetera and display
the time like you show. After a minute the magnets turn off and the mobile continues,
randomly.
I say this 'cause I like random, and I worry that the engines would wear out. Totaly
deserving of this croissan |
