Systems and methods for providing a scalable graphical user interface. In an embodiment, the user interface comprises a main display area that includes a timeline across a first axis and a set of content (e.g., media and/or applications) categories along a second axis that is orthogonal to the first axis, such that each content category is associated with a row or column across the timeline. As each content is created or consumed, the timeline is populated with a selectable representation of the content in the row or column associated with the content category corresponding to the content at a point on the timeline representing a time at which the content was created or consumed, such that the content is accessible to a user via the representation of the content.
