I agree that thought should be given to this, but I would suggest an
8-spoke wheel instead of 6-. That way the wheel can be emulated on a
keypad (with key 5 being the hub). That idea is by no means my original,
but I've used it well enough playing Neverwinter Nights to have acquired
an appreciation for it. NWN uses transparency, too, so it's kinda nifty.
In fact, I suggest checking out their implementation. If one is using a
finger on the NWN interface, then it would require lifting the finger to
tap at each spoke and the idea is tapping on a spoke brings you outward
in the hierarchy and tapping in the hub brings you down.
