Sandscape

A falling-sand sandbox

Sandscape is a 3D sandbox for PC built around a small floating world and a falling-sand simulation. You shape the terrain, pour in materials, and watch them flow, burn, grow, or react. Sand piles up, water collects behind banks, and fire spreads through dry grass, leaving embers behind.

There’s no timer or score to chase. You can build a castle and flood it, set a forest burning, or leave the world running and see what has changed when you return.
