In the above article on page 90 there is a misprint. The word Showcase should have read SHOWPLACE. SHOWPLACE is a nod to the early days of Pixar.
Before Toy Story, Pixar went through several incarnations prior to becoming a movie studio, including selling software. In fact, Pixar's SHOWPLACE was one of the first consumer-oriented 3D programs for creating computer graphics.
SHOWPLACE was discontinued when Pixar chose to concentrate on film production instead of application development.
