We've been developing a freekick game in Flash that utilises the best of Papervision and JiglibFlash.
JiglibFlash is a C++ port of a physics engine that has support for Papervision, Away3D and Sandy3D. The basic concept here is to score a goal. You can have a bit of fun along the way by knocking over the defenders in the wall and seeing them tumble.
Use the mouse to aim and click when ready to strike.
