The focus of the book is on short vector-based animations, although of course BASIC is much too slow to render them in real-time. Then again, the target audience of the book are, at least according to the subtitle, graphic designers and such, who would presumably have the necessary equipment to send completed frames to a plotter or store them on video tape.
Three sample programs from the book are shown below. The actual source code in the book also has comments of course.
