Hey! What’s up? I’m still digging for old samples I made with Adobe Flash (Sorry again, iOS devices!), and the free physics engine called Box2DFlash. I found samples I made to explore the physics engine capabilities, and I decided to put them all together and showcase them as virtual physics playgrounds. You can rearrange both static objects and objects affected by gravity, and you can throw them to explore how they behave and are affected by other objects, gravity, and fluids.
