Just thinknig about physics and physics engines...
At the moment I'm writing a game that has very simple physics (i.e. acceleration in vertices) and simple collision detection (i.e. intersecting rectangles). There are no inter-object forces (i.e. things don't bounce off each other).
I was thinking of "upgrading" the game to have a smarter collision detection method (i.e. using the image edges rather than the containing rectangle)...
nvm just found a cool tool...

Thanks
