The most common form of projector embedded in urban environments today is the media façade. Media façades may feature screens, lights, actual projectors and other technologies that broadcast images and/or sounds. Design with media façades involves not only choosing a technology and location for a screen, but also working with the media that is being projected into a space. Content may be asynchronous or synchronous; when synchronous content is projected into space people sometimes call it a simulcast. When media façades begin to determine the fundamental character of a place, rather than add to it, one may refer to the creation of an immersive environment, especially when the content being projected is sampled from the environment itself.
