A book is provided which comprises front and back covers (12,14) and a plurality of pages (16) bound between the covers. A plurality of the pages (16) each have an aperture (18) and the resulting plurality of apertures cooperate with the back cover (14) to define a recess (22) extending through the pages. The book further comprises a container (24) attached to the back cover (14) so as to be located in the recess (22). The book may have multiple recesses and associated containers.

A toy includes a body having a first side representative of a first body appearance, and a second side opposite the first side and representative of a second body appearance different from the first body appearance. The toy also includes a head coupled to the body, the head being reversible between a first face and a second face, the first face corresponding to the first body appearance and the second face corresponding to the second body appearance. When the first face of the head is exposed to view, the second face of the head is concealed from view inside the head, and when the second face of the head is exposed to view, the first face of the head is concealed from view inside the head. The toy further includes a book coupled to the second side of the body.

A fluid transference system, including: (a) at least two inflatable objects; (b) at least one variable-state fluid transfer conduit, interposed between a first and a second inflatable objects, the variable state conduit configured to allow fluid flow there-through in an open state and to disallow the flow in a closed state. A fluid transfer system, including: (a) an entry port; (b) an exit port; (c) a unidirectional main conduit defined between the entry port and the exit port; (d) an intermediate port; and (e) an intermediate conduit defined between the intermediate port and the main conduit, intersecting the main conduit between a first unidirectional valve and a second unidirectional valve, the main conduit defining a unidirectional fluid flow.

A virtual reality viewer may be integrated with printed materials, such as pamphlets, flyers, magazines, or books. A user may be able to review the printed material regarding the advertised products or services and then activate a virtual reality scene on an electronic display, such as the user's mobile device, that provides the user with more information regarding the products or services. The virtual reality viewer may be attached to pages in the printed materials and constructed in a manner such that the viewer pops up when the pages are opened. The user may place a mobile device in the viewer and/or access an integrated display to view a virtual reality scene related to content in the printed materials.

The present invention proposes a dot pattern on which code information and x and y coordinate information can be defined even if the dot pattern is extremely small, and proposes an information reproducing method and an information reproducing device based on the dot pattern. More specifically, a medium such as a printed material on which is formed a dot pattern portion by arranging in accordance with a given rule dots generated by a dot code generating algorithm in order to recognize various kinds of multimedia information is scanned as image data by scanning means. Then, the image data is converted into code data. Multimedia information corresponding to the code data is read out of storing means to be reproduced.
