TEDxCalgary video: Subverting the Walls

Last June I gave a talk about subverting walls for TEDxCalgary. In it I spoke about to men who defeated walls in Ceuta and Palestine by physically going over them, and about two artists in Arizona and Ramallah who subvert walls by transforming them through art.

The video of my talk is now online. Thanks to the people at TEDxCalgary for producing and posting this video, and for honouring me with the invitation to speak at their event.
