Look at the fish tank on the left. It looks as though there are two illuminated panels in the back of the tank. In fact they are reflections of two panels that have over-exposed on the right of the picture. This form of partial reflection in glass is a good way of getting images to appear in remote places. If there were a screen on the right of this image, all you would see would be the reflected panels and if the originals were laterally inverted, you could have the information appear in the tank. This method was used for special effects in Victorian theatres and was known as Pepper's Ghost.
