Disrupting the Selfish Interface. The screen, the mobile device, the personal computer, the network node: the devices that mediate our interactions are individualising by their very nature. What alternatives, or tactical repurposing, might allow-for, encourage or demand collaborative interactions?

Personal++ Computer disables individual computer use: it deactivates the screen unless a minimum of two users are present.
— The Multi-User Keyboard requires two or three users to begin using the computer.
