To save space and time, pictures gradually became stylized and ultimately evolved into characters. Cave Drawings and Early Language Development As societies became more complex so did languages; and as travel brought people of different cultures together, written languages evolved further to be more versatile. Hundreds of characters could be narrowed down to a select set of "letters." An entire language could then be represented using various combinations of letters. Perspective Drawings Through observation, artists sought methods to portray images of the world around them. During the time of the Renaissance, perspective (space and depth relationships) became a very important part of the desire to produce realistic images. Maps A map is a flat representation of a 3D space. The item can be as large as our solar system or earth, or as small as chromosomal genes.

Different kinds of Maps Gene Map –Shows locations of specific genes in DNA Floor Plan – Shows rooms in a building. Photography The development of photography depended on understanding the physics of light to record images and chemical processes to produce permanent images. The improvement of materials (celluloid film) and processes allowed everyone to enjoy the photographic process. This process allowed the pictures to be recorded on an easy to use medium. Television With the invention of television, images could be brought into the home. Television combined sound with motion and eventually color was added.
