I was thinking today, what would be needed to create the uttermost ultimate sandbox in real life?
Well, it should be inventing a material that can somehow be turned into either water, sand, a viscous liquid, and a solid, and colored however the user wishes. That would be very awesome.

Reminds me of problem sleuth pluggable window lightsource and portal.
