Jonah Brucker-Smith, artist/researcher at Media Lab Europe (the MIT Medialab kind-of franchise, worth to check what is happening there :) proposes a collection of background awareness applications based on desktop ubiquity : Desktop Subversibles : - MouseTraces : a background graphical display of mouse movements between two people across distance. - ClipIt! : a networked sticky-note application that provides ambient glimpses of the copy and paste activity of other users - MouseMiles : a networked collective mouse milage indicator manifested in physical space. - Clicks : a distributed mouse click collector rendered as sound in public space.
