Systems and approaches provide for user interfaces (UIs) that are based on a user's viewing angle and/or motion and orientation of the computing device. The UI elements of the framework can be rendered based on head tracking and/or device motion/orientation data to provide a user the impression that the UI elements exist in an environment having three-dimensional (3D) depth. To further enhance the impression of 3D depth, UI elements positioned at depths perceived to be closer to the user can cast shadows upon UI elements positioned at depths appearing to be further away from the user. During the course of operating the computing device, the depths of certain UI elements can change. The UI elements can be rendered to correspond to such changes in depth, and shadows for the UI elements can be recast to be consistent with the rendered UI elements.
