I love when I trip over stuff rather than having it served up to me via Google’s silver platter service.
Over on DeviantArt we have Tasper’s homage to Myst, ala The Tempest:

I’m at work so I don’t have much of a change to play it, but I couldn’t not link it. How often do we get a Tempest game?
It's not very good. For something more interesting, check out the Macbeth site in Second Life, the virtual world "game." It's creepy and an interesting attempt to catch the mood of the play in a digital landscape.
