Presented by a startup that has chosen, not surprisingly, the name Invisibility Shield Co. , this invisible panel is nicely presented as a tool for "Entertaining friends and hiding from friends". The authors have already packaged 25, but are looking for funds on the popular crowd funding container to expand production to a wider audience by guaranteeing an affordable cost, a simple assembly procedure once received and also two formats with the small one equal to from 310 x 210 mm and the large one of 950 x 650 mm. How does this invisibility cloak work?
You can only faintly notice the hands of those hiding behind the cloak
Each cloak uses a grid of precision lenses that bounce diagonally off both sides sides a good part of the light reflected by the subject towards a point away from the observer. The lenses are oriented vertically so as to make much brighter what is far from the observation point (the background, so to speak) and less what is closest to the surface. As you can see from the image above with the hands gripping the panel, however, the parts almost in contact are still visible. In short, a technology that is certainly not perfect, but it works in a surprisingly positive way considering the prices that are not so exaggerated.

It is still possible to finance the project and take home one of the few invisibility cloaks that will be produced in this first batch. The standard version costs 299 pounds or around 350 euros, while the miniaturized version costs 49 pounds or around 60 euros. Shipments to all over the world will start next December.
