eL Seed: Street Art with a message of hope

Thinking about the upcoming mural workshops with cmap in the Dunkirk camps I looked out this inspiring TED talk from artist eL Seed who paints huge murals in public spaces of poems and peacful messages written in Arabic using his own special script "calligraffiti" - so beautiful - I wonder can we use this as reference?

I'm also curious to know if either of these images seen in the street on Lily's Alterntive London street art tour are anything to do with eL Seed... or maybe by folk inspired by him?
