semiotic_pirateTalk about your awesome clocks with weird formats! I'm thinking it would be neat to have this in a wrist watch but... would you be able to read the dial?? Each number has three nines configured in a mathematical formula designed to give you the appropriate number for that position on the clock.

A clock for math whizzes
by Stephen Shankland
Math enthusiasts who don't want to move totally into the digital realm might appreciate this analog clock.
Each number is expressed as a calculation involving three instances of the number 9.
For example, 5 o'clock is the square root of nine (3), factorial (3x2x1 = 6), minus 9/9 (6-1 = 5).
The trickiest time is 7 o'clock, whose calculation works out to 6.99999..., with an infinite number of nines. Wikipedia assures us that 0.99999... really does equal 1, so no worries that the clock is cheating there.
While we're on the subject of archaic clock technology, how come clocks and watches with Roman numerals represent 4 o'clock with IIII rather than the traditional IV? A friend told me it was because it was easier for illiterate people to comprehend, but I'd love to see some history about this.

But it doesn’t say how I can get one!
And how would 1984 open? “It was a bright cold day in April, and the clocks were striking 9 + root(9) + 9/9.” Not quite the same ring to it.
Astropixie called it the:
clock of nines
the 7 o'clock isn't exactly equal to 7, but i dont mind rounding up.... i'm not that big of a nerd! cool clock!
and found it here, while someone commenting on Astropixie found it for sale on Cafe Press. It comes with the single AAA battery it takes to run it. It is a representation of the Triple Nine Society emblem - the swirled image at the center of the clock. They're a super-smart club.
Am I thorough or what?
