Using an LCD’s poor viewing angle to your advantage
I wonder if this may have come a bit late to be useful - I can't see that colour inversion effect on my laptop monitor even at fairly extreme angles, so I'm not really confident that it's going to work on here. The advance in LCD technology may prevent this seeing any serious adoption, although I do think the "unread emails" one is pretty nifty. I'm not so sure about the banking one since I'm very unlikely to do any banking with someone sitting nearby, even if I knew a technology like that was in place.
