Abstract: A system and a method are disclosed for transmitting a physical representation from one location to another location. Components included in a mobile computing device can be used to detect that a physical action has been performed, and to simulate physical representations. In one embodiment, a first user sends a physical representation using a mobile computing device. The user receiving the physical representation is asked to perform a physical action. The second user's mobile computing device then detects that the physical action has been performed and simulates the physical representation the first user sent.

Abstract: A content feed aggregator displays an ordered list of content items, including a selected item and a set of other items. The selected item is displayed in an expanded format while the other items are simultaneously displayed in a compact format. At least one respective item in compact format is displayed above the selected item and at least one respective item in compact format displayed below the selected item. In response to a user action for selecting a second item in the displayed list, the ordered list of content items is redisplayed with the second item displayed in the expanded format and the other items, including the first item, displayed in the compact format.

Abstract: A label may be applied to one or more content items by a user or in accordance with predefined criteria, rules, or filters. The labeled content items are associated with a secondary feed associated with the label. Other users may subscribe to the secondary feed and be presented with the labeled content items. The label may be system-defined or user defined. A label may be applied to a content feed in order to apply the label to the content items in the content feed.

Abstract: Additional content items that satisfy predefined criteria with respect to a user-selected content item are identified. The predefined criteria may be that the selected and additional content items have particular characteristics that are the same. Information corresponding to the selected and identified content items is presented to a user. Characteristics based on which additional content items may be identified may include data type, source, and absence of content. The information may be presented in a gallery view, which can be a thumbnails gallery for images or a playlist for digital audio or video.
