A target of Syria's intelligence agency, Mohammed had to flee. Now the graffiti artist is developing an online game based on his escape - the user is able to put himself in the shoes of Zaytoun, the little refugee who finds his shelter destroyed and his family gone: Where to go?

Irene's concerned about the web. The Mexican opposes technological control and surveillance. "I think my generation still dreams about becoming famous, being on TV.
