Surf in privacy.

This was the catchphrase of a certain Internet Cafe back in the dear old hometown, back in those happy days when very house did not have a computer and the only place to watch, ahem, unmentionable websites was with friends at the neighbourhood cyber-cafe. Very much in that spirit is the now-defunct 'Invisible Browser' Ghostzilla, which blends into the open window of any other MS-Windows application, like, say Outlook and only appears when you run the mouse over it. Leaving any Peeping Tom with the impression that you are busy checking email, while you could be actually visiting, ahem,.. any website. Oh, that cafe I talked about... it had each surfing booth screened of by curtains...
