This is directed to dynamic tags or screen savers for display on an electronic device. The tags can include several dynamic elements that move across the display. The particular characteristics of the elements can be controlled in part by the output of one or more sensors detecting the environment of the device. For example, the color scheme used for a tag can be selected based on the colors of an image captured by a camera, and the orientation of the movement can be selected from the output of a motion sensing component. The tag can adjust automatically based on the sensor outputs to provide an aesthetically pleasing display that a user can use as an fashion accessory.
