Abstract: A graphical user interface manages a user's electronic assets using a common protocol and displays such assets to the user using a common framework and interface. The graphical user interface includes a bar of segmented geometric structures and a set of one or more elongated streamers positioned, respectively, to form an “L-shaped” interface. The segmented geometric structures include individual “cards” that represent one or more electronic assets or groups of electronic assets stored accessible to the user. The user can share one or more of such cards via secure peer-to-peer communication without any need for uploading or attachment. The set of elongated streamers can display links to online content, advertisements targeted to the user, links to locally- or remotely-stored electronic assets, reminders of future events, and notifications of shared content. User activities can be tracked and provided to one or more third parties.
