1. A method comprising: receiving, by a server computer from a client device, an indication that a graphical user interface (GUI) on the client device is at a first zoom state associated with a cellular environment, the cellular environment configured for providing a spatial arrangement or spatial configuration of a plurality of category cells in a two-dimensional or three-dimensional space on the GUI, the plurality of category cells representing various categories of information; for each category cell of the plurality of category cells, resolving a content reference associated with the each category cell and the first zoom state, the resolving performed by the server computer and comprising: querying a data source to identify a category name for the each category cell; and obtaining a snapshot of one of a plurality of web pages associated with the category name; displaying the plurality of category cells in the GUI on the client device; receiving a user interaction with a first one of the category cells, the user interaction changing the zoom state of the GUI from the first zoom state to a second zoom state; responsive to the user interaction with the first one of the category cells, determining a subset of bookmark cells to display in the GUI at the second zoom state; for each bookmark cell in the subset of bookmark cells, resolving a content reference associated with the each bookmark cell and the second zoom state, the resolving comprising: querying, using the content reference associated with the each bookmark cell, a uniform resource locator (URL) to obtain content for a web page; responsive to the user interaction with the first one of the category cells, displaying the subset of bookmark cells with the content obtained using the URL in the GUI such that the subset of bookmark cells displayed in the GUI at the second zoom state present various types of contents relative to the first one of the category cells; and converting the various types of contents to a common format prior to displaying the subset of bookmark cells in the GUI at the second zoom state.
