surrounding an opening therethrough, and at least one at-least-partially-rear-facing surface of said accessory-interface structure clamps against a corresponding at least one at-least-partially-front-facing surface of said front housing portion of said image projector surrounding said opening therethrough. ### Claim 5 (depends on 1) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 1, wherein the operative coupling of said at least one projector-attachment structure to said accessory-interface structure provides for resisting relative motion of said accessory-interface structure relative to said image projector. ### Claim 6 (depends on 1) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 1, wherein said accessory-interface structure provides for pivotally attaching to a lens assembly about an associated pivot axis that is transverse to an optical axis of said image projector along which abeam of light is projected. ### Claim 7 (depends on 6) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 6, wherein said accessory-interface structure provides for locking an angular orientation of said lens assembly about said associated pivot axis. ### Claim 8 (depends on 1) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 1, wherein said region of said front housing portion is associated with an opening therethrough for projection of an associated beam of light from said image projector. ### Claim 9 (depends on 8) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 8, wherein a projector lens of said image projector extends through said opening through said front housing portion of said image projector, and said at least one projector-attachment structure axially extends through a radial gap between an outside of said projector lens and inside of said opening through said front housing portion. ### Claim 10 (depends on 8) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 8, wherein when assembled to said image projector, a front-most portion of said at least one projector-interface structure is recessed relative to said accessory-interface structure. ### Claim 11 (depends on 8) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 8, wherein a transverse position of at least one said at least one projector-attachment structure is adjustable relative to said accessory-interface structure. ### Claim 12 (depends on 8) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 8, wherein said accessory-interface structure is operatively coupled to each projector-attachment structure of said at least one projector-attachment structure with at least one fastener. ### Claim 13 (depends on 10) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 10, wherein each said at least one fastener cooperates with a corresponding threaded hole in said projector-attachment structure. ### Claim 14 (depends on 10) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 10, wherein at least one said at least one fastener operatively coupling said at least one projector-attachment structure to said accessory-interface structure is located above a center of a projector lens of said image projector. ### Claim 15 (depends on 14) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 14, wherein said accessory-interface structure incorporates at least one time proximate to a base portion of said accessory-interface structure, a forward-facing portion of which provides for engaging with a rearward-facing portion of said front housing portion through a base portion of said opening through said front housing portion of said image projector. ### Claim 16 (depends on 12) An image-projector accessory-attachment adapter for attaching an image-projector accessory to an image projector as recited in claim 12, wherein said at least one projector-attachment structure is arcuately shaped and extends over a circumferential span, a first portion of said at least one projector-attachment structure provides for axially extending through said opening through said front housing portion of said image projector, said at least one projector-attachment structure incorporates, on a rear side thereof, at least one first arcuate segment having a diameter greater than a diameter of said opening, said at least one first arcuate segment provides for abutting a rear surface of said front housing portion of said image projector, said at least one projector-attachment structure incorporates, on a front side thereof, at least one second arcuate segment having a diameter greater than said diameter of said opening, and said at least one second arcuate segment provides
