During the 2019 Sorry, Not Sorry festival, Graffiti vzw and Piazza dell'Arte matched local youngsters with an experienced street artist, in this case A squid called Sebastian.  Together they created a mural, from design to the actual execution.

Smartphone users were also catered to: youngsters gave the wall an extra dimension with augmented reality.

The style of A squid called Sebastian shows recognisable influences from the comic world and the work of figurative masters. He always seeks out a certain dynamism and tension in his work through his use of colours and composition.
