Diorama table

I was amazed by this creation when I went to the Science Center for a visit. It's known as a Diorama table and the image are actually projected from above. Amazing and interactive.

Cars appear where there is a spoon

Twist the rope into a circle and you get a pool of water and ducks swimming inside it.

The rope become a railway tracks and you can see train traveling on it

Place a saucer and a cup and a "town" forms before your own eyes

To understand what I mean you have to read this and watch the video too. But it would be better if you go there and experience it yourself. :)
