TEDxThessaloniki took place on April 2nd, 2011 at the Olympion Cinema in Thessaloniki, Greece. 

Their theme was "Why Not?" --  taken from the quote "Some men see things as they are and ask why, others dream things that never were and ask why not?"

In the weeks before the event, the TEDxThessaloniki team collaborated with producers at HelloKinetic to create a short promotional video about cultural activism -- the teaser follows a mysterious woman dressed in black creating an interesting and potentially dangerous contraption.
