The starting point for the MassAge MessAge website project is Marshall McLuhan's media theory and his book The Medium is the Massage. The website aims to make McLuhan's theory tangible and accessible to users by translating it into an experimental experience that combines interactivity and media-theoretical reflection. The focus is not on the content, but on the medium itself as a message and instrument of perception. Users actively shape the content and design elements of the website, causing the medium to change constantly. Finally, a web-to-print function enables translation into a physical medium, the poster, thus questioning what remains when interaction becomes surface.
