WiiPhysics is a physics playground for the Wii, much like Crayon Physics or PocketPhysics. It uses Box2D and libwiisprite.

Changes:

+Added fully scrollable world with ground
up, down, left, right to pan (Or just move the pointer to the edge of the screen)
+Added minimap for scrolling around world
+Added ability to fix camera to an object for easy following around world – Hit 1 on any object to attach camera (works best on circles and squares) – (To detach, just hit 1 anywhere on the screen)
+Added sky, with dynamic clouds – (You now know when you are in freeze b/c the clouds stop moving)
+Fixed jumping of rectangles on draw
+Lots of bug fixes
