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.
Somatic is a generic 3D puzzle solver for soma and pentomino-like puzzles. For an arbitrary set of pieces and a figure with not more than 64 cubes, it can check whether this figure can be built using these pieces and return one or more solutions. It can also solve split figures that are not connected and partial figures, which do not need all pieces to be built. Piece sets that can be solved include but are not limited to the soma cube, the somaplus set, the doublesoma set, the bedlam cube, and the pentomino set.
