This is my "working" replica of a Myst linking book. It's made out of a copy of the same book Cyan originally scanned as a texture reference, with a hand-assembled computer hidden inside that's fast enough to play Half-Life 2 at 30fps+. It plays all the Myst games (including the latest 3D ones).

Note: the video has been sped-up in a few places to improve its flow with the music, but there was no other digital trickery or blue-screen effects. It's all real.
