Although our lives depend on plants for virtually everything that keeps us alive (oxygen, food, fibers, lumber, fuel, etc), their lives remain a secret to most of us. The reason is simple - plants live on a different time-scale from ours. Although not usually obvious in the relatively hyperactive activities of humans, plants are in constant motion as they develop, search for light and nutrients, avoid predators, exploit neighbors, and reproduce.
Ski Stunt Simulator may very well be my all-time favorite physics game. As with most physics games, the premise is simple: You control a 2D skier performing various tricks on the slopes. Where Ski Stunt Simulator stands apart from other physics is the fidelity of that control. This isn't a simple ragdoll game-far from it. In fact, Ski Stunt Simulator is the result of collaboration between a programmer at Relic Entertainment and a researcher at the University of British Columbia, and the robust simulation definitely demonstrates an academic level of engineering.
