Possibly this is not the most important feature needed in Mudbox, but the mudbox icon looks exactly like the Maya Icon when pinned,( I am a 3DS MAX user, but I ask for this, thinking in the Maya users).
And in fact, Mud need an unique and distinctive logo and icon.
I vote for come back to the old good one "Fox" logo:
