WabbelLab is a game were one has to roll a ball
through a maze without hitting one of the holes.
The nice thing about this game is that it is not
controlled with the keys but with help of the
camera. The camera is used to determine the tilt
of the phone - and the ball will always roll into
the direction in which the phone has been tilted.
It was developed for the Nokia 3650 but seems to
work also on other phones with similar hardware
like the 7650.
