Kind of like I was assuming, people are definitely thinking about a magic wand metaphor for physical user interfaces.

This is something I'm finding a lot more plausible than user-interfaces based on sophisticated 3D graphics derived from game technology. And I'm going to be reading OrangeCone regularly from now on.

I wonder how hard would it be for DragonMother or Alferian Gwydion MacLir to put a simple LED in a wand?
