So I took Brian's suggestion a bit too seriously and decide to make my own B10 logo. Let me know what you think, and let's use this thread for any logo submissions.
A couple of things: The "i" is divided into 12 pieces. The piece that looks like it has a raging inferiority complex represents michigan state. The arrogant one is us. The gradient at the bottom was included to represent the rich past, steadily moving into an exciting, wide-open future. The "Ten" is intentionally in a somewhat more elegant font than you'll see on any other conference logo -- it's intended to represent a collective focus on academics that is largely unique to the Big Ten. The lightish blue, sadly, is there out of neccessity. The other options were pink, teal and brown.
Yes, I know this was a bit of a waste of time.
