The invention of the current application is directed to a 3-dimensional viewing device with stereoscopic affect including a main linear body including at least one inner lining layer, and a mirror assembly. The at least one inner lining is positioned within the main linear body and the mirror assembly is positioned inside the main linear body where the perimeter of the mirror assembly is surrounded by the at least one inner lining. The mirror assembly includes at least two mirrors. The 3-dimensional viewing device with stereoscopic affect also includes an image holder assembly including a gear assembly, and an endcap including a viewing hole. The endcap is attached to a first end of the main linear body and the second end of the main linear body at least partially inserts into an opening in the image holder assembly.

A light-sabre type accessory comprises a tubular blade including a tube with a proximal end and a distal end. The accessory also includes a handle having a sleeve with first and second ends, into which is inserted a control unit controlling at least one lighting source lighting the tubular blade. A system for removably fixing the tubular blade on the handle through its proximal end includes a mouthpiece fitted to the proximal end of the tube and a clamping ring engaged to be fitted onto the mouthpiece and fixed to the first end of the sleeve. The mouthpiece also includes a shoulder able to abut against the first end of the sleeve and the sleeve includes, from its first end, a well in which the mouthpiece is engaged up to its shoulder, the clamping ring being engaged from the distal end of the tube to be fitted onto the mouthpiece.

A decoration is disclosed, which includes: a light source emitting light in at least two directions; a transmission member having an eyeball pattern; and a projection member; the light emitted by the light source in at least two directions passes through the transmission member, and projects the eyeball pattern onto at least two positions on the projection member. Another disclosed decoration includes: two sets of light sources, each set of light sources emitting light in at least two directions; two transmission members, each transmission member having an eyeball pattern; and two projection members; the light emitted by each set of the light sources in at least two directions passes through the transmission member, and projects the eyeball pattern onto at least two positions on the projection member. The decoration has simple structure and diverse functions, and produces a visual effect of moving eyeballs by means of projection for decoration applications.

A 3-dimensional object may contain tunnels passing through the object so that when the object rotates, if the object is viewed from a certain angle, the tunnel is only visible for the moment that the tunnel is pointed directly at the viewer's eye. This system of tunnels can be used to create an animated system of dots when the shape rotates, and the dots can be positioned so that they create the animated illusion of dots moving along the surface of the shape in the opposite of the true direction of rotation.

An underwater retrieval game system employs a submersible target having a combination of features that make it difficult to locate underwater. The body portion of the submersible target is translucent and has a density greater than water. The target may be tossed in a swimming pool and sink to the bottom. A game player may jump into the water and try to locate the target. A combination of additional features such as size, shape, and surface texture may make it more difficult to spot the target underwater. A submersible target may comprise a detection device, such as a small light, that is activated after a certain period of time or is activated remotely by a wireless signal. A game player may be challenged to find the targets before the detection device is activated, for example.
