Obstacles, 2013, consists of an interactive 9x15 foot platform made up of 15 individual articulated concrete tiles. Each tile has the ability to tilt by 27 degrees in two directions thus creating a changing surface on which any participant is invited to become a part of the piece and ultimately an impromptu performer. The working title for the piece is Obstacles. The platform includes speakers, an amplifier and piezoelectric contact microphones embedded in the support structure to emphasize every tilt, creak and thud. A passerby cannot quietly or anonymously cross the walkway. Alternately, our daily routines are truly and decisively interrupted and destabilized as every move is amplified drawing public attention to the user and heightening the sense of removal from an everyday experience in public space.
