Here Not Here is a public artwork specially commissioned for the Student Centre at University College London and can be seen by the public at any time. In Here Not Here, two large ultra-bright LED screens simultaneously show passers by the countries represented and not represented by the UCL student body at any given time. Both information streams update in real time in endless rotation, and are presented side by side in identical decorative grids; the left hand screen showing us who is "here" and the right hand screen showing us who is "not here."
Fluid colour changes and the gentle abstraction of the text as it scrolls through each grid helps to provide a hypnotic framework within which to contemplate and re-see the meaningfulness and meaninglessness of every country in the world.
