This brings a smile to my face everytime! You can tell the time, only if you solve the math equation!! What a great gift for that math geek you know and love! (via decor craft inc.)

Man, I already have enough trouble telling time as it is!

chalk board? can you erase those and add your own formulas?

The site only describes it as a "blackboard 'looking' face", though, it would be nifty if thier was a clock where you could design your own numbers..patent it xD

I would buy this for my artsy sister just because it would stress her out so much. But in a funny loving way, not in a mean evil way. Perhaps it would help all of us to stay a little more sharp while out of school.

You've never had to work this hard to tell the time. It's a clock with impossible (for me) math equations. However, a math dork would, inevitably, find this hilarious.

If you can solve the math problems on this clock, then you will have no problem figuring out what time it is. All that thinking would give me a migraine.

AWESOME clock. Ok, maybe I'm just a nerd and most people don't appreciate doing math to figure out the time - but in case you haven't learned how to tell time without a digital clock, then you have bigger problems.
