Once A Wall, or Ripple Remains is the last fold in an on-going experimental documentary project which began in the summer and fall of 1998 in the Occupied Territory of Palestine, and which spans close to ten years to date. It employs a wide range of media (from single channel video, CD-ROM, website, to written text, 3-D animation, and interactive installation). The various media reflect and undermine each other???s reports, detecting gaps, contradiction and bias in the perception and mediation of the series of encounters which set the trail of records in motion. Together these records form a manifold document that questions the stability of any rendering of such encounters.
