Private Viewing...
I know it'll never fly, 'cos it's prior art and there's no patent dosh in it...
For years we men have had modesty barriers on some urinals. How about popout / inflatable side barriers for laptops. Should go down a treat with the airlines.
Yeah, ok, it's late and I'm taking the pi**.
Raises the interesting philosophical question though as to why some urinals are more "secure" than others. Now THERE'S an excellent subject for some arts post grad grant funding. Should be worth a couple of dozen phds at least.
