I think it's pretty safe to say that you have never seen anything like this before. I certainly hadn't.
On this clip from Ukraine's version of "Britian's Got Talent," a young artist recreates the story of Germany's WWII occupation of Ukraine on a lightbox covered in sand, accompanied by music. Sounds weird, I know, but check it out. I was blown away by how quickly she's able to create faces and scenes in the sand and how powerfully it all comes together.
I wonder if she got her start by playing in sandboxes as a kid?
