An excellent, if non-transparent, introduction to fractals, with emphasis on computer graphics. Includes detailed algorithms in "pseudo-code" (approximately Pascal) for drawing Julia sets and the Mandelbrot set, as well as simpler fractal shapes such as the Koch snowflake. The book is studded with high-resolution images that are impressive even in the present day, and astonishing for 1988 (the date of publication). A note of warning: most of the material is written for students with a strong background in mathematics.
