A piston for an internal combustion engine has a piston head, a piston skirt, and a circumferential recess configured between the piston head and the piston skirt. The performance variables are statistically simulated over subset combinations of variables based on pin information for the module. Embodiments of the visual display system can be used in numerous applications, including head-up displays for automotive, tracked and rail-mounted vehicles, marine, aerospace applications, see-through speech prompt displays, and see-through projection displays.
