Holographic Storm

The Holographic Storm is a demonstration of how light can be shaped using nanostructured plexiglass plates.

It looks as though there are flashes of lightning behind the plates. But are they real or is it just an illusion?​

In fact, it is an illusion, similar to that of a magnifying glass. What happens if you look, for example, at a beetle through a magnifying glass? The magnifying glass changes the light that passes through it in such a way that it seems we are looking at a much bigger beetle.


Thanks to the sophisticated technology, we embossed the pictures in nanoscale into metallic microparticles. Now you have the most beautiful buildings of Dubai and Prague on the tip of your finger.
