9. The apparatus of claim 7, wherein the bottom layer is affixed to the touch screen at one or more localized attachment locations, whereby tent-like shapes can form in the bottom layer when the bottom layer is moved in a lateral direction.
10. The apparatus of claim 7, wherein the elastic top layer has the same lateral position in the first and second states of the overlay structure.
11. The apparatus of claim 1, wherein the overlay structure is substantially transparent to visible light.
12. The apparatus of claim 11, wherein the overlay structure includes two or more transparent materials having substantially matched indices of refraction.
13. The apparatus of claim 1, wherein the touch screen is capable of providing a visual display that is visible through the overlay structure.

15. The apparatus of claim 1, wherein the actuator comprises an actuator selected from the group consisting of: magnetic solenoid latch, micro-relay, and bimetals.
16. The apparatus of claim 1, wherein the touch screen senses touch via electrical capacitance.
17. Apparatus capable of being disposed on a touch screen, the apparatus comprising:
a) an overlay structure configured to be disposed on a top surface of the touch screen, wherein a vertical height direction is perpendicular to a top surface of the touch screen, and wherein lateral directions are parallel to the top surface of the touch screen, wherein the overlay structure is capable of being actuated between a first state and a second state by a mechanical force applied in one or more lateral directions to one or more lateral edges of the overlay structure; and
b) an actuator capable of actuating the overlay structure to be in the first state or in the second state;
wherein the first state of the overlay structure is a configuration wherein the overlay structure has a substantially uniform top surface;
wherein the second state of the overlay structure is a configuration wherein the top surface of the overlay structure has increased z-height, relative to other parts of the overlay structure, at one or more predetermined lateral positions; and
wherein the touch screen is responsive to touch provided to the overlay structure at the one or more predetermined lateral positions when the overlay structure is in the second state.
