The clock you need an engineering degree to read

Readers, you can probably instantly figure out every one of the equations on this Pop Quiz Clock, but I'm having trouble with 6 x 2. Oh, wait a second, we don't need no stinking equations to figure out what time it is — it's an analog clock!

So how much is this kooky clock that I'm considering sending to my high school math teacher? Why, it's a mere 229,00 Swedish Krona, or in U.S. dollars, that would be the square root of 900 x 2 - 1770. Okay, okay, it's $30., via Red Ferret
