I would love to read up on how that works, because right now it is magic to me.
Me too!
It would appear they are using the second camera lens to get some 3D definition, but even that makes me look around for someone wearing a wizarding robe and carrying a willow wand with a phoenix feather core.
If I do see Hermione or Harry around I think I will ask them for a bit larger targeting pointer. Even with plastic lenses in my eyes the one they have now can be really difficult to pick up against a visually busy background.
