Box2D for the Wii!
I am pleasantly surprised by how easy it is to get started with coding for the Wii! As a first little project, I ported the Box2D physics engine and made a little demo app called Box2DBalls (source included).
I think the Wiimote and Box2D play together very well. There are a lot of possibilities for fun 2D physics games, so go make some! :)
Box2DBalls comes with source code. Check the Readme for instructions on compiling Box2D for Wii. It’s dead simple!

Why using fixed numbers on Wii ? It has hardware floats support !

As I said in the Readme, I’m just afraid of FPUs. No, just kidding :) Adding the float target to the Makefile is as simple as replacing wii-fixed by wii-float and removing the -DTARGET_FLOAT32_IS_FIXED flag.
