On the face of it, there's something very strange going on...
These people and their blank expressions have caused a real stir.
Their visits included Elton John's ball and the Harrods summer sale, with one photographer saying: "It's the weirdest thing I've ever seen."
They use a membrane of artificial skin with tiny holes over the eyes so they can see. Theories include them being part of an ad campaign, artists or celebs sick of the paparazzi.

Whoa, I would be totally freaked out if I saw something like that!
I think its part of promotion for a movie, because these "faces" are appearing at major public events, like Wimbledon.
Is there anyone here from London? How do our British Interferencers feel about this?
