I imagine this would take the form of about a 12" lcd and digital camera. The camera would allow you to take a photo of the back of your head to check stray hairs etc. you could also use it to record video messages for your housemate.

       This is somewhat smaller, but I think we did the all-around mirror (using screens) before.   

       Btw, no stray hairs on the back of my head!

       Frankly, I think the less I see of the back of my head, the better.

       LSD mirror? :)

       How about just two mirrors, one reflecting the back of your head, into another which faces you? It -would- be quite a bit cheaper, and higher resolution to boot! Not to mention it has an infinite color bit-depth ~_^.

       I'm not sure it's possible to have an infinite color bit-depth, due to the quantum nature of light.
