Abstract: Various aspects and embodiments are directed to a streamlined computer device and a graphical user interface that organizes interface elements into views of computer content for presentation to a user. Various views of digital media content permits users to easily and efficiently access various digital media content. Different views are used to provide an interface that is responsive to configurations of the device and responsive to activity being performed by the user. Aspects include permitting the user to maintain and manage digital media content libraries. According to some embodiments, the libraries comprise user digital media content and references digital media content. Functionality provided to a user can be tailored to the type of content displayed, accessed and/or managed. According to various aspects, methods and systems are provided for accessing and managing digital media libraries on a streamlined computing device with a plurality selectable I/O profiles.

Abstract: Effective, non-invasive and non-destructive systems and methods provide an appearance of increased whiteness and/or brightness of the teeth, thereby enhancing the appearance of the teeth. One or more residual colors or dyes are applied to the surface of a tooth in order to complete the color spectrum of the tooth surface or more closely complete the color spectrum of the tooth surface, thereby enhancing the appearance of the tooth since a complete color spectrum appears as white. In one implementation, a residual color includes a shade of violet, wherein a red-violet reduces the yellow appearance of the tooth and a blue-violet enhances the brightness of the tooth. In one implementation, a bleaching step is performed to the surface of the tooth followed by the application of a residual color onto the surface of the tooth. In one implementation, a residual color includes a yellow shade applied to the surface of a tooth that otherwise appears gray to cause the tooth to appear whiter.

Abstract: A tooth whitening system that effectively conceals tooth discoloration within a short period of time. The system includes a single, spectrally pure, substantially violet dye and a carrier for applying the dye to teeth.
