[Wear-Hard] Perhaps a cheaper HMD

[Steve Barr]

This demonstrates taking a video feed from a
camera on an HMD, processing it, and
displaying the result on the HMD:

I wonder if that's a low-cost way to go for some
people: add the GUI they want to a video
stream and display the result on mass-produced
i-glasses like devices.

I assume there's been some work on this sort
of idea, but a quick search found nothing.
