Re: Use cases
Actually, I think there's already a game of that style. It's based on the old "marble box maze" with the plate that could be tilted forward/back left/right using twisty knobs, the result being that the marble would then roll down various tracks, & if you did it wrong then the marble fell down a hole & you had to start over.
The Android game did the same thing but used the tilt sensor to mimic the knob action (narf narf!) & roll a virtual marble around the screen.
Otherwise the bendy screen version could make the game even more difficult by adding a 3D version that required manipulating your balls (naaaarf!) on one side of the bend for the horizontal and on the other side for the vertical.
I'll get my coat, it's the one with the pockets full of marbles. =-)p
