TABI have released a nice, neat and simple game called FlyBy, it looks good and plays well and is just a little addictive, at 59p in the app store its a good way of wasting a little of your life

The creators describe it thus:

FlyBy is about flying in mid-air on a bright sunny day among bumble-bees and bubbles and sunbeams (quietly, or you can listen to your own music). At start you select the traffic congestion to suit your preferred excitement level. It varies from calming relaxed cruising to highly exciting drive. Then you start flying – just use the accelerometer to change flying direction. You should avoid bumble-bees. You don’t want to hit those cute dummies, do you? Besides, when they hit you, it costs you points (5) and causes condensation and moss to grow on windshield. Too much moss (3 pieces) on the windshield and the game is over. Bubbles, on the other hand, should be hit. Hitting them gets you points (2) and missing them costs you points (1). Rainbow on a bubble signifies that you are about to break your best score if you hit it – congratulations. Flying through sunbeam clears the windshield (condensation dries up and moss falls off), also if your result is negative, it is reset to zero points.

Anytime you can tap to re-calibrate the tilt position – tapping causes the current tilt to be assumed as the straight flight direction.
