Math clock

Not sure where this clock came from but it's a fun way to tell time with math formulas... It would be simple to make your own with any cheapo clock kit - [via] Link.

Ikea sells a wall clock (RUSCH) here for $3 that could be re-purposed (its not available for web order unfortunately):

I bought a similar clockworks on sale(reduced due to discontinue) at one of the local WalMarts, about six months ago... my cost $4.99 (no they didn't have the 97 cent ending, thats why I remember so vividly)as I said, it was discontinued, but I believe the original price (under the $5 sticker) was $10 something so the above item (at $13 to $12 based on quantity discount) is a reasonable price for those who don't live in IKEA country (only has stores in Seattle, Houston, and one of the San's in California)BTW: that IKEA $3 clock is of course a discontinued item thus the ultra low price

The clock is from the Triple Nine society (and hence why each hour is made of three 9's).
Entry into the society requires that you've placed in the top 99.9% percentile on at least one of a list of standardized tests.

qazwiz - I am not sure where you are, but there are more than 3 IKEA's in the US. Here in the Twin Cities there is a very nice store near the Mall Of America. I am not a huge fan of their furniture or culture, but there are some excellent Maker opportunities there if you keep your eyes open. I bought 3 of these clocks on a recent trip for the purpose of ripping them apart as soon as I got home...

You can get small desk or wall clocks at the dollar store - 1$ for the mechanism and hands. I have not had a problem with quality of the mechanisms in these clocks - they last just as long as others. The ones at my particular dollar store are easy to hack and flip the plate to run it backwards, too.

Not a continuous movement, but fairly cheap...
