Playing with the idea that many forms of modern technology have depersonalized the experience of communicating with others, I modified an LCD screen to allow for two people, sitting opposite one another at a table, to have a text-based chat session with other. The screen is (mostly) transparent, allowing for the users to see the person they chat with as they type.
The screen is visually split into two parts. One of the user’s words will appear on the top and the other on the bottom. As each person types, their words will appear backwards to themselves, but forwards to the other person. Only one person can type at a time, with the cursor passing back and forth between the users as soon as they hit Enter.
