Happy Pi Day everybody!  I’ll be out celebrating with the rest of the NYC Data Mafia eating pizza and devouring the above Pi Cake, custom baked by Chrissie Cook.

Today is also Albert Einstein’s birthday so there are plenty of reasons to have fun.

The cake below was my first ever Pi Cake in what is sure to become an annual tradition.

Update: Drew Conway does far more justice to our fair, irrational, transcendental number.

Update 2:  Engadget posted this awesome video of “What Pi Sounds Like.“
