Pick Your Tools. Set Up. Let Gravity Do All The Work.

SimplePhysics, as the name implies, is a simple physics simulator. You can use it to suspend objects of various weights, shapes and sizes atop structures like houses or densely-packed, and see the results play out with some attention to detail. Although it might not be a great choice to use for heavy-duty industrial projects, it can be amusing both as a game and as a utility to try out ideas of what might happen if you try putting something together.
