Sand in a Box : Pixel Magic

Sand in a Box is a falling sand simulation app. Just touch the screen to see how grains of sand fall and form stacks. Just try it and you see how fun it is to form landscapes out of sand or watch the water flow.

Features:
- Sand Physics: Watch how sands falls and interacts with walls and elements
- intuitive controls: touch the screen to "paint" the sand.

- Different colors of sand!
- Fluids: water and oil, with different colors that now can be mixed together!
- 8 special elements: acid, lava, TNT, bacteria and more.

Version 4.0 introduced new simulation algorithm. As some reviewers suggested, they liked older version better, so we're reverting to original simulation from 2011 and we make it even better. Now particles move more freely making simulation more dynamic and there's no more randomization involved in simulation.
Version 5.00 takes it even further introducing many new elements to play with, 36 in total from just 4 from previous releases.
Box has no bottom anymore, particles that fall on the bottom will appear on top. If you're thinking with portals you know what I mean. Now you can create endless waterfalls or sandfalls and redirect particles in any way.
