I would choose, the math clock I bought at Austin, TX.
Why??? Come on Look at it! Take in all its awesomeness. If you don't our family, then you don't know that all of us are gifted with math. (with my mother as an exception). So this Clock, isn't a item that says nerd. (1) its an ice breaker (2) its a torture device (3) its us.
So....whats your favorite thing in your home?
