Youngblood analyses the works of Jane Veeder who from being a video producer has turned into a computer artist. Veeder tries to handle computer animation in an experimental manner - being photographically realistic in her works is of little interest for her.
Veeder works in ZGRASS a language written by Tom De Fanti exclusively for real-time interactive motion graphics. Incorporating the best features of Pascal, Smalltalk, Lisp and BASIC. ZGRASS is by all accounts the best graphics language around. Among other things, it is self-teaching and user-extensible - the users can create their own commands and integrate these command into the language, expanding and evolving it to fit their personal style of making images.
ZGRASS runs only on the Datamax UV-1 Graphics Computer which contains three custom chips designed for Bally Arcade games like Wizards of War and Gorf - one chip for processing instructions, one for controlling the display, and one for sound synthesis. This makes ZGRASS faster than anything around at its price (about $ 10,000), and speed is essential for real-time animation. There's also a 16-screen memory that allows you to create and store sixteen different full-screen images and then call them up in a real time animation cycle. Output is standard NTSC video.
