I did see someting similar done with a xbox360 kinnect in "moomin world" in Turku, Finland last year..Never heard of this game before and it looks really unique, thanks for sharing. Will be keen to see pics if anyone builds this up at their home.
I think these use "kinetic sand", which you can purchase from a toy store or find a recipe to make your own. It sticks to itself, making it easy to form and sculpt with. Doesn't make a mess as it bonds together. Only thing I would be unsure about is if the inspection camera system expects a specific color...Something about this intrigues me but I fear that my whole game room would be full of sand, and my cat would find another use for the play area
