Jonathan Guberman of Toronto’s Site 3 coLaboratory hackerspace wrote in to share his Automatypewriter project:

Introducing the Automatypewriter, a new way to experience interactive fiction! It’s still a little rough around the edges (in particular, you can see that the spacebar sticks a little, and the whole thing needs to be tidied up), but you get the idea: the Automatypewriter is a typewriter that can type on its own, as well as detect what you type on it. By reading what it types to you and responding, it can be used interactively to play a game or participate in a story (in this case, Zork).

See the project page for technical details.
