A few examples of some experimental Flash projects using Actionscript. Focusing mainly on physics engine and natural motion models.

Actionscript coded Zombie Invasion Simulator demonstrating an extremely efficient use of actionscript.
Using a grid system to reduce the number of hitTest calculations per frame allows for 20-30fps with 150 active sprites on a standard desktop

Collision detection and physics modelling to give an arcade-style pool game. Not quite complete, but playable.

Randomly generated terrain, and random motion of the sheep on the terrain.
Use the mouse to throw them around, to test the physics engine.

A rotatable icosahedron using the Flash Drawing API and a backface culling algorithm for speed.
