This project, by Jonathan Guberman, is interesting from the Tangible User Interface perspective as it physically types the words onto the same piece of paper as you are typing on. In short, this means that the input (your typing) occurs through the same physical means as the output (the computers typing)… this is in contrast to the laptop, where there is a disconnect between the users input (on the keyboard) and the computers output (on the screen).
Anyway, in addition to being interested in the project from the TUI perspective, it also happens to play Zork as shown in the video below:
