Abstract

Disclosed herein are exemplary embodiments of a projector having multiple projection paths and related methodology.

Claims

1. A projector comprising:

a housing defining an interior and an exterior;

a first projection path extending from said interior to said exterior;

a second projection path extending from said interior to said exterior;

a light source positioned in said interior, said light source capable of creating a visual;

wherein said first projection path is aligned with said light source; and

wherein said second projection path is aligned with said light source.

2. The projector of claim 1 and further comprising:

a beam splitter positioned in optical communication with said light source,

wherein said first projection path is aligned with said light source via said beam splitter; and

wherein said second projection path is aligned with said light source via said beam splitter.

3. The projector of claim 1 wherein:

said first projection path is fixed relative to said projector; and

said second projection path is adjustable relative to said first projection path.

4. The projector of claim 1 wherein said first projection path is transverse to said second projection path.

5. The projector of claim 1 wherein said first projection path is perpendicular to said second projection path.

6. The projector of claim 1 wherein said first projection path is parallel to and oppositely disposed relative to said second projection path.

7. The projector of claim 1 and further comprising:

a port for receiving data representative of said visual.

8. A method for presenting a visual, said method comprising:

generating a first visual emitted from a projector along a first projection path;

generating a second visual emitted from said projector along a second projection path;

projecting said first visual onto a first wall; and

projecting said second visual onto a second wall.

9. The method of claim 8 wherein said second visual is identical to said first visual.

10. An apparatus comprising:

a means for projecting at least one image;

a first projection path extending from said means for projecting; and

a second projection path extending from said means for projecting, said second projection path being directed in a direction different than said first projection path.
