This is a super-rough hardware sketch of what a mechanical Twitter feed might look like. I’ve been playing with ideas around combining digital projection with mechanical motion and this is a prototype to test some of the ideas.

It consists of a series of people I follow on Twitter represented as their user photo printed out and suspended in space. Next to that hangs a blank speech bubble that is attached to an electric motor which is in turn controlled by an Arduino microcontroller that can re-position the speech bubble by winching it up or down.
