Uber Geeky Wall Clock

Ever wondered, just how geeky are you?  Here is a clock that will test your nerdy street cred.  The Math Pop Quiz Clock separates the n00bs from the 1337s. See how many you can figure out before cheating. If you having a problem with most of these, go back to school!

Found another one to flex your geek cells – a blend of the two would make a real Uber Nerd Clock, check it out after the break.
