Golf simulation system

A golf simulation system comprising:

• a screen with a projection surface;
• a ball path analysis device configured to predict a path of a ball struck by a club of a user;
• and
• a green simulation apparatus having a configurable upper surface with a changeable contour, the apparatus comprising:
• a plurality of movable surface elements positioned in a close array and each forming portions of the upper surface, each of the surface elements having a top surface forming a respective portion of the upper surface, each of the surfaces elements being elongated with a longitudinal axis;
• wherein the top surface of a said surface element has a perimeter and the perimeters of adjacent surface elements defining a gap therebetween, the perimeters being configured such that the gap between the perimeters is substantially uniform;
• and
• wherein the surface elements are movable in the longitudinal direction to adjust the position of the top surface, the surface elements having a neutral position, the top surfaces of surface elements in the neutral position defining a reference plane, the surface element having a plurality of raised positions in which the top surface is located vertically higher than the reference plane;
• wherein the gap between the surface elements is such that side surfaces of the surface elements abut against side surfaces of adjacent surface elements.
