Last month I purchased a new unibody 15" Macbook Pro. It is my first Mac in over 10 years. It's so nice owning a Mac again. I've been dabbling in iPhone development since I got it, and I have a basic OpenGL application working. My app lets me move a marble around the screen using the Macbook's accelerometer.

I used the accelerometer simulator
code.google.com/p/accelerometer-simulator/
and the unimotion program unimotion.sourceforge.net/ to accomplish this. It would be nice to have this functionality built into the iPhone simulator.

I bought a book about game physics, and I'm on my way to creating a great game. Next I will be simulating interactions between multiple marbles, and figuring out how to load level configurations.
