Projection of interactive game environment

A computer program product comprising one or more computer-readable media having thereon computer-executable instructions that, when executed by one or more processors of a computing system, cause the computing system to perform the following:

• an act of detecting a user interaction with a game environment image that is projected on a substantially horizontal surface, the projected game environment image including a visual representation of at least part of a virtual game environment space in which a plurality of virtual objects are spatially positioned;
• and
• an act of changing the projected visualized representation in response to the user interaction with the visualized representation.

A surface-top game environment projection mechanism comprising:

• a projector mechanism that includes an image supply mechanism and at least one projector, the image preparation mechanism configured to supply a game environment image to project in response to received data that represents a plurality of virtual objects that are spatially positioned in a virtual game environment space, the at least one projector configured to project the game environment image supplied by the image supply mechanism, the projected game environment image including a visual representation of at least part of the virtual game environment space, the visualized representation include a visualized representation of at least some of the virtual objects;
• and
• a scanning mechanism configured to scan the area projected by the projected game environment image to determine one or more positions of a real interactivity input object.
