@foone and the age old standard problem of: parts cost way too much.

Probably with a dash of a decent chance of eye damage if you fuck up the brightness, but hey if you could make it you can free up the lap space to: just a keyboard with either trackpad or some kind of mouse and you can use it from positions you can't use a laptop from from.

But I did say it was a worse idea before laying it infront of you.

@foone I have a significantly worse idea for the display, a pair of glasses set up with micro projectors (the tiny displays for other eye based displays) set up with lenses and on a pair of glasses with a black bg. Effectively a wearable display but not transparent, eliminating most of the issues with them and introducing new fun and interesting problems like:

having a fragile collection of wires lenses and displays on your face in bed,
and having a wire to get wrapped around you by accident
