For six years hobbyist Mike Ando has been working on an exact replica of a linking book, an item that warps players between areas in the adventure series Myst — only Ando's book can actually be used to play the computer games.
The video above shows Ando's book in action, a 135-year-old tome gutted and rigged with a full desktop computer, which is running a copy of the realMyst remake for PC with modified touchscreen controls. Ando notes that the hardware inside the book is "capable of running Half-Life 2 at 30fps plus," and contains all Myst games in its memory.
Ando is selling the item for $15,625.
