See Thru Laptops2
From the MAKE Flickr photo pool

Wow – Flickr user Kap4001 removed the displays from 5 laptops just to . . . wait, no he didn’t –

Every screen is showing exactly whats behind it – relative to the camera, which was on a tripod.
The most difficult task was to convince the old powerbook 180 to show a simple jpeg.. netscape navigator 3 did it.

Man, why do I always fall for that one? – see-trough laptops! on Flickr
