A Pop Quiz Math clock! Don’t look at me – I don’t have a clue what any of these math equations mean (are they even equations?). But it’s a pretty awesome clock, if you want my opinion.

We’re going to be late, it’s almost half past pi!"

If I had a quarter for every time I heard that. Don’t know what I’m talking about? Well, my friend you are in desperate need of the Pop Quiz Clock. It will help you study up on the most rudimentary of advanced mathematics. Know a math or science teacher? Well now you have the perfect gift for their classroom. Know just an everyday geek? Well now you have something they can put between their Star Trek and Battlestar Galactica posters.
