CHAPTER II - Mode 13h
Graphics on your computer are made of tiny dots called 'pixels' (short for picture elements). Each pixel has a colour. In our modern age they're so close together and so tiny that they're effectively invisible on their own - grouped together, they seem to form shapes, images, and text. Animation is produced by changing the images these pixels form very quickly. Each image is called a 'frame'; films are projected at 24 frames per second (fps), TV at 30fps, and modern computer screens at around 60fps.
(A screen shot of Super Mario Bros. on the left with an enlarged view on the right, so you can see how the image is formed from pixels)
