Friend wrote this iPhone game which got on the AppStore today,
it is called "Journey Home".
Simple but addictive - goal is to get the spacecraft into the wormhole,
with the help of gravitational force from planets, and in later levels,
recoil force by firing a missile.
IMO it is a cool app for someone to understand the concepts of gravity
and inertia. Grateful for your support - the app is just selling at $1.99 at the moment!
