Cyan Worlds has released a free version of its classic 1993 puzzle adventure Myst on the iPhone.
Myst Free is restricted to the exploration of Myst Island, but still weighs in at a substantial 123MB - so that it can cram in all those haunting, static images.
If you want to explore the full five Ages of the original game, it's currently on sale and will only set you back Ł2.99.
Myst's relationship with Apple is a long one - it's that rare beast, a game that was originally released for Mac before PC. Although it has subsequently been ported to virtually every system you can imagine.
