A mount for attaching a projection device to an overhead structure, the mount comprising: - a device interface operably attachable to the projection device; and - a device orientation adjustment structure (44,46,48) operably coupled with the device interface, the device orientation adjustment structure (44,46,48) including at least one upright (44, 46) extending from the device interface and a support structure interface extending from and operably coupled with the at least one upright (44, 46), the support structure interface adapted to be operably coupled with the overhead structure, the at least one upright (44, 46) and the support structure interface having cooperating guide structures (132,180, 165, 202) defining a first axis of rotation (X-X), the support structure interface including a first portion and a second portion, the first and second portions (168, 170) of the support structure interface operably coupled so as to define a second axis of rotation (Y-Y) generally transverse to the first axis of rotation (X-X), wherein the device interface is separately selectively shiftable about both the first and second axes of rotation (X-X, Y-Y) when the support structure interface is fixedly coupled with the overhead structure, and the mount further comprises a single selectively adjustable friction element, wherein loosening the friction element enables the device interface to be shifted about the the first axis of rotation (X-X), and wherein the friction element can be tightened to frictionally resist shifting of the device interface about the first axis of rotation (X-X), characterized in that neither of the first and second axes of rotation (X-X, Y-Y) extend through any portion of either the device interface or the device orientation adjustment structure (44,46,48) and in that the mount further comprises a single selectively adjustable friction element, wherein loosening the friction element enables the device interface to be shifted about the the first axis of rotation (X-X), and wherein the friction element can be tightened to frictionally resist shifting of the device interface about the first axis of rotation (X-X). - a device interface operably attachable to the projection device; and - a device orientation adjustment structure (44,46,48) operably coupled with the device interface, the device orientation adjustment structure (44,46,48) including at least one upright (44, 46) extending from the device interface and a support structure interface extending from and operably coupled with the at least one upright (44, 46), the support structure interface adapted to be operably coupled with the overhead structure, the at least one upright (44, 46) and the support structure interface having cooperating guide structures (132,180, 165, 202) defining a first axis of rotation (X-X), the support structure interface including a first portion and a second portion, the first and second portions (168, 170) of the support structure interface operably coupled so as to define a second axis of rotation (Y-Y) generally transverse to the first axis of rotation (X-X), wherein the device interface is separately selectively shiftable about both the first and second axes of rotation (X-X, Y-Y) when the support structure interface is fixedly coupled with the overhead structure, and the mount further comprises a single selectively adjustable friction element, wherein loosening the friction element enables the device interface to be shifted about the the first axis of rotation (X-X), and wherein the friction element can be tightened to frictionally resist shifting of the device interface about the first axis of rotation (X-X),
