On the outside, this maybe to be just another book based on Myst, but on the inside, there is something really interesting indeed! A fully working self contained computer with touch screen display that runs on 3 cell Lithium-Ion batteries, which will last for up to three hours.
These are details according to the video provided by the designer Mike Ando;
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 desktop computer inside it. For more pictures & tech specifications, check out http://www.riumplus.com/mystbook
Even though this is a one off design it is for sale, but be prepared to part with $16,000 (£10,000) for the privilege.
