4D, whether used in a scientific or artistic sense, brings about the thought of time. The movement, flow, and progression of time. In the instance of art, time can be portrayed in several different medias in several different categories, making it a very broad spectrum to work with. Some of the most popular could be an animation, music, video, or a sculpture that moves. Any piece with interactive properties or simply anything that suggests time could be an example of 4D art.
