Chaos theory has found applications in areas as diverse as population dynamics, computer graphics and weather forecasting. The related topic of fractals gives rise to computer-generated pictures of exquisite depth and beauty, resembling landscapes, trees and flowers. Now, anybody with access to the power of an Amiga computer can explore this new field. Conrad Bessant explains the necessary mathematics in the simplest manner, with complete BASIC (Amiga, Hisoft and GFA)listings, ready to use on any Amiga, but readily adaptable to other computers. The contents include:

• Order and Chaos: how randomness can giverise to ordered patterns.
• Strange Attractors: concepts and illustrations to clarify this new topic.
• The MandelbrotSet: two-dimensional and three-dimensional versions.
• Julia Sets: their relationship to the Mandelbrot Set.
• Fractal Landscapes: sample programsand stunningpictures.
• Imitating Nature: cell culture, plants, shrubs and trees.
• Conversion notes: for BBC and Archimedes computers
• Disk offer: with all the listings to save the labour of typing in the programs!
