The very first cable weather "channel" was a large circular base at least 4' diameter (don't remember exact size, but big) that had various full size gauges on it. A camera was positioned to look down on the gauge under it. The whole table top rotated so that each gauge would continuously cycle under the camera. When you viewed the channel, you'd have to wait until the gauge you wanted to see rotated back around.
