Chapter 18: Contract Law. Just as property law is concerned with creating legal rights, and tort law and criminal law with defending them, contract law and related legal fields are intended to provide for the orderly transfer of rights from one person or organization to another.
A picture, also called an image, is a group of coloured points on a flat surface that looks the same as something else. For example, a picture can look the same as an object or a person. Pictures can also be drawings, paintings or photographs. People who make such pictures are called artists, photographers or painters. Pictures are very helpful.
A hologram is a picture of a whole object, showing it in three dimensions. We've all seen cheap holographic images on credit cards and ID cards (where they help prevent copying). Far more impressive are large holograms that take the form of a ghostly 3-D moving figure that you can walk around to see from all angles.
