Abstract: A computer-implemented method and system for realizing an interactive, virtual bookshelf representing physical books and digitally stored books of the user. Using a search query, the Web is searched using search metadata to identify a desired book. Library metadata corresponding to the physical books and digitally stored books of the user is then searched using the search metadata to determine whether the desired book is present in the virtual on-line bookshelf. Results indicative of whether the desired book is present on the virtual on-line bookshelf can be displayed.

Abstract: A cube shaped toy has a button and a rotary switch on each of the cube's six sides. For each of the cube's six faces, there is an associated set of four tones. Pushing the button on a selected face causes the toy to play the tones associated with that face. In particular, if each face is divided into four quadrants, there is one "quadrant-tone" associated with each quadrant. The toy has just six distinct tones, and when the toy is first turned on, or restarted, all four tones for each face are identical. Whenever one of the rotary switches is turned, the quadrant-tones of the associated face are rotated, and the quadrant-tones for the neighboring faces are also "rotated", generating a new set of tone patterns for each of the five affected faces. By listening to the tones for each face and rotating the rotary switches, the user can move the quadrant-tones until all four tones for each face are identical.
