The phone's screen is a small window into a "vast" universe. You've just loaded a passenger and he told you which planet he wants to go to, but you have no idea of where that is. So from now on, in Easy and Medium difficulty levels, you'll see a yellow arrow bouncing in the direction of the destination planet. On Medium, the arrow is only there for 3 seconds.
I've also changed the menu background from a 3 layer parallax of some really wide images of stars to a particle emitter and some nebulae images. It has a clean synthetic look, and the stars move individually and more fluidly.
