A kaleidoscopic display assembly, comprising: (a) a stand; (b) a kaleidoscope tube supported by the stand; (c) a display container in alignment with the kaleidoscope tube for containing at least a first botanical specimen viewable in a kaleidoscopic pattern through a viewing opening of the kaleidoscope tube; and (d) an aroma container positioned alongside the tube and enclosing an aroma chamber for containing a second botanical specimen. The aroma container has one or more scent ports extending therethrough for sampling an aroma of the second botanical specimen during viewing of the kaleidoscopic pattern.

A system for dynamically projecting a logo onto a surface includes a light source, moveable lenses, and an actuator. The light source emits light toward the surface. The lenses are positioned with between the light source and the surface, with each lens having multiple transparent portions configured to permit some of the emitted light to pass through the lens in a corresponding light pattern. Each corresponding light pattern forms a different part of the logo. The actuator moves the lenses with respect to the emitted light in response to a control signal to thereby cause projection of the logo onto the surface. A vehicle includes a body having a door, road wheels in contact with a road surface, and the system which projects the logo onto the road surface proximate the door. The controller may be programmed to execute a method for projecting the logo.

A slide actuator includes: a fixed member; a movable member movable to the fixed member by a predetermined stroke in a predetermined direction; a plurality of balls interposed between the fixed member and the movable member and configured to movably support the movable member; and paired elastic bodies disposed at both ends of a moving range of each of the balls, each of the elastic bodies being configured to come into contact with the corresponding ball when the balls move with movement of the movable member.

Multiuse devices and systems for warping images for viewing. as well as related methods. In one illustrative embodiment, such a system or device may include a body comprising a tube and a slot structure, configured for supporting a portable electronic device. The tube may include a first front viewing end and a second image source end, which are connected by a bore stretching the length of the tube. The inner surface of the bore may be formed as a reflective surface. The slot structure may include a shelf and a backing member that define the slot. In some illustrative embodiments, the system may include a mechanism for securing a mobile device in the slot to serve as an image source or as a video recording device.
