If you have ever been to a trade fair that was bigger than your backyard, you may have seen some magic 3D projections floating in space, wondering how on earth this might be possible and why it is so dark there.
I saw this in many variations, on the International Automobile Exhibition as a mapping on cars or on Gamescom in smaller boxes om game consoles. Theme parks use these in ghost trains. These smaller boxes are for example offered by http://www.holocube.eu/
. I googled the magic behind these boxes and it was ridiculously easy.
So wonder no more, I will show you how to make a mini-3D-projection for less than a dollar (unless you have no smartphone, then it will be about 181 dollar)
using exactly the same technique.
I know, this looks photoshopped, but trust me, it's not.
