Provided are a magnetic fluid composite for display use which enables visually recognizing a subtle shape caused by a spiking phenomenon and which can exhibit a color other than black, and a magnetic fluid composite display device.

A magnetic fluid composite 1 for display use contains water 10, an oily magnetic fluid 20 and poorly magnetic light shielding pieces 30.

The light shielding pieces 30 have a flake shape and include respectively hydrophilic layers 31, light shielding layers 33 and hydrophilic layers 35 that are laminated in the written order.

The light shielding pieces 30 are arranged along the interface 1i between the water 10 and the oily magnetic fluid 20 so that the interface 1i between the water 10 and the oily magnetic fluid 20 is covered with a number of the light shielding pieces 30.

A magnetic fluid composite display device 2 includes a transparent container 40 including a glass container main body 41 and a resin lid 42, a magnetic fluid composite 1 placed inside the container, and a permanent magnet 50 configured to apply a magnetic force to the magnetic fluid composite 1.

A flying disc device appears to “flutter” in flight when rotating. The design is interesting and visually appealing when in use, is easy to see in flight, and can be easily retrieved when laying flat on the ground or another flat surface owing to its angularly oriented dual-disc design.

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.

An image display device includes a transparent plate which may be disposed in an inclined manner with respect to a display section of a portable terminal provided with the display section. A display displayed on the display section may be reflected on the transparent plate. A space behind the transparent plate may be viewed through the transparent plate and, at the same time, an image on the display section of the portable terminal may also be viewed while being reflected on the transparent plate.

A projection device for projecting images on a surface of the device includes an outer housing having a front translucent screen, a projection module frame mounted on an inner surface of the outer housing, and a projection roller frame supported by the projection module frame. The projection roller frame includes first and second spaced apart rollers rotatable respectively on two opposite cylindrical ends integrally formed on a lampshade. A cylindrical projection film is held between the first and second rollers. A light source is mounted inside the lampshade so that an image formed on the projection film can be projected on the front translucent screen by the light source. The device further includes a gear mechanism for driving the rollers, a position-limiting mechanism, and a speaker.

A portable system is provided for engaging users during play by presenting one or more images provided by a mobile computing device. The system includes a projector configured to visually output the one or more images delivered by the computing device. The system also includes a mount for supporting the projector, and at least one lens that is coupled to the projector. The system further includes a housing having at least a first and second illuminable surface that can receive images projected by the projector. The surfaces can be moved between a collapsed condition and an operative condition.
