DSDN142 - P3 Idea Changed + Other Interactions

So, stepping away from the "game elements" in my current code and removing them completely to become more "toy" like. So because of this I begina to look into other means to create a sense for interaction that didn't involve "goals".

My first idea for development was to create an objects that interacted with the background of the current sketch, so as shown below, a gird that somewhat deforms as the ship moves across the surface.

Problem?
ship moved by mouseClick +  mouseDrag, not very interactive in the end, so idea dumped and back to the drawing board with other ideas of what possibilities I can create with this "ship".
