Twitten is a two-minute film utilising a series of still images taken over a three-week period, observing Boundary Passage set between Brighton and Hove, East Sussex. Twitten is the Sussex word for alley. The piece was inspired by Italo Calvino's Invisible Cities and film makers George Albert Smith, Mark Leckey and Woody & Steina Vasulka.

The music is The Waltz, courtesy of composer and pianist Alessandra Celletti, taken from her recent album, Sacred Honey.
