Requires a PowerPC Macintosh running OS 9 (not OS X in Classic mode) and a video-input device. Type a number from 0-9 to select a different variation. To quit the application, hold down the Command-key, 1-key, and 0-key simultaneously.

Mirror Mirror was in the works since 1995 but was too ambitious in its use of video input as the primary means of interaction. By 1998 computers had advanced far enough, however the publisher of Digitalogue fell ill and this book was never completed.
