5. A green simulation apparatus having a configurable upper surface with a changeable contour, the apparatus comprising:

a covering forming the upper surface;

a covering support assembly configured to support the covering, the support assembly comprising:

a plurality of movable positioning elements having the covering resting thereon, the plurality of positioning elements being positioned in an array extending in a reference plane, the positioning elements being movable along axes extending substantially perpendicular to the reference plane, the positioning elements being elongated with a longitudinal axis; and

a movement actuator configured to move at least one of the positioning elements independently of other positioning elements in the array;

wherein the plurality of positioning elements includes active positioning elements and passive positioning elements, the active positioning elements being associated with said movement actuator and the passive positioning elements not being associated with said movement actuator; and

the covering support assembly additionally comprises a locking assembly for selectively locking at least one of the positioning elements in a selected movement position.

6. The apparatus of claim 5 wherein the locking assembly is configured to act on at least one passive movement element of the array of movement elements.

7. The apparatus of claim 5 wherein at least one of the positioning elements includes a pin having an exterior surface, a plurality of recesses being formed on the exterior surface of the pin along at least a portion of a length of the pin, and the locking assembly comprises a lock element actuatable to engage at least one of the recesses formed on the at least one positioning element.

8. The apparatus of claim 7 wherein the at least one positioning element is said passive positioning element.

9. The apparatus of claim 7 wherein the lock element comprises a lock plate with an aperture through which the pin of the at least one positioning element extends.

10. The apparatus of claim 9 wherein the locking plate is movable to position a portion of the locking plate in one of the recesses formed in the pin of the at least one positioning element.

11. The apparatus of claim 10 additionally comprising a guide with a guide aperture through which the pin of the at least one positioning element extends, the locking plate being movable with respect to the guide between a lock position and a release position.

12. A green simulation apparatus having a configurable upper surface with a changeable contour, the apparatus comprising:

a covering forming the upper surface;

a covering support assembly configured to support the covering, the support assembly comprising:
