Invisible screen
A screen on which human eyes can only see an uninterrupted white surface. You can only see the full picture using special glasses. The screen can be implemented in decorations, walls, etc. We are able to produce and modify (the size) the technology on our own. It can be perfectly used for campaigns with a message like this - we see things in a different way, you will see through it with us, see the future as we do, etc...
