This, is a genius idea, not only is it 2-sided (look at diagram pictures in link) but it is unique, figured I would post this here to get the attention of the Arduino Users. Also, the Biscuit board is just as amazing for a prototype board.
Here are the URL's without the extra quotes:
ReonBalisty:
Cake Board Kickstarter
Biscuit Board Kickstarter
Why didn't I think of that 
My bad, did not paste very well, cross-posted it from the Teensy forums.
