It reminds me of Islamabad airport. Back in 2001, I passed security and I saw a weird reflection of the screen on the glasses of the security officer.
I glanced over his back and sure enough, the guy was looking at a screen full of moving snow particles, with a rolling picture, just like a badly tuned TV screen. No view of the xray'd material, though.
And that was at the height of the worldwide airport security increase after 9/11.
