Many of the videos and demonstrations discussed in The Invisible Gorilla are available for use in talks, presentations, and teaching on DVDs from Viscog Productions, Inc. One of these DVDs includes the original "Gorilla in our Midst" video discussed in Chapter 1 of the book and another includes the "door" study described in Chapter 2. Both DVDs have many other examples illustrating the ways that we can misperceive our world. These DVDs are the only form in which any of these videos are available for use in presentations.
