Mindwheel was an impressive interactive fiction created by Synapse/Broderbund back in 1984, authored by former Poet Laureate Robert Pinsky. I am currently reading Pinsky's translation of Dante's Inferno, and it is interesting how lyrical, and yet claustrophobic and in places even creepy Mindwheel can be, much like Pinsky's Inferno.
This download is a Windows port, and what's really cool is it has been made available by Steve Hales, the lead developer for the project, and apparently also designed the audio sub-system in the ultra cool T-Mobile SideKick. From his about page:
"If anyone remembers: Fort Apocalypse , Slime, Dimension X, I coded and designed them with Ihor Wolosenko. I also coded and co-designed Mindwheel with Robert Pinksy, the famed poet and author. Working with Robert changed the way I read and write words forever. He was writing History of my Heart during the development of Mindwheel, so they have familiar themes. You can even get a deeper meaning behind Mindwheel, by reading this book. Although, he claims, they are not connected."
