During another workshop week with Roel Wouters and Jonathan Puckey at the Rietveld Academie we were asked to make a poster machines. It either had to consist of a mechanical construction, a set of rules or a game. I was working together with Julia Bendeler and Elki Boerdam. We didn't want to spend our time programming this week so we looked for a participation driven tool.
We placed each poster under a webcam that and filmed and streamed it live. Via social media we invited people to tune in to our videostream. On the poster we placed 5 cellphones with a little paint vehicle. By calling a phone, the participant would cause it to vibrate over the poster, leaving a trace of ink.Funny enough it catched on and we made many posters with the help of many many phonecalls. It had a kind of addicting effect to finish the circle you were making or to drive another phone from the poster.
