Cloaking device uses ordinary lenses to hide objects:

It struck me that this work may just be an ingenious application of a well known principle of optics design. Most good lenses used in photography have variable diaphrams placed somewhere between the optical elements. When you take a picture the lens's aperture or diaphram is "invisible" in that it doesn't show up in the image. Only the scene that lays in front of the first lens appears in the image that is focussed on the film or digital sensor.

Some interesting playing-around-with-lenses.

Too bad it's not a real cloaking device, but rather a "sabotage" of the camera,

and in a time where we stream live recordings for entertainment it's unlikely we need to play around with lenses like this for any reason.

(Now if the cloaking device itself would be invisible to a passing observer ... shouldn't be hard to pull off expanding on what they already made)

Seems interesting.

They could make a giant lens , and make everything on the other side invisible! (For both Entertainment and Military purposes)
