MoSketch

MoSketch is an Etch-A-Sketch analogue written in MoSync. The background
is gray. The pointer is white. Use the arrow keys to move the pointer
and draw a black polyline. Press 9 to clear the screen. Press 2 to
“lift” the pointer, or to put it back down. Press 0 (zero) to exit the
program. The sketch is saved to a permanent store automatically when
you exit the program. If a sketch has been saved, it will be loaded
automatically when you start the program. The MoSketch example
highlights usage of MoSync’s storage API and the exit notification.
