Abstract: Devices and techniques are generally described for providing a graphical user interface. In some examples, first image data may be sent to a computing device, that when rendered is effective to display a first combination of items disposed together in a first environment and a first selectable control. In some examples, first data may be received indicating a selection of the first selectable control. In various examples, a first computing device may determine first feature data representing the first image data. In some examples, the first computing device may determine second image data using the first feature data. In some examples, the second image data may be sent to a second computing device. The second image data, when rendered, may be effective to display a second combination of items disposed together in a second environment.

Abstract: Techniques for updating a graphical user interface (GUI) are described. In an example, a system provides, to a user device, a GUI element about an item and linked to a page. The user device is associated with a user account. Based on a selection of the GUI element, the system provides the page to the user device for presentation in the GUI. The page is configured to present one or more GUI objects in a main window, where these GUI objects are associated with one or more items based at least in part on the user account. The page is also configured to overlay a modal window over at least a portion of the main window. The modal window is configured to present a GUI object corresponding to the item. The web page is also configured to dismiss, based on a user interaction, the modal window.
