Chaos by French artist Mephisto aka Laurent Menuet @mephistodesign at @laschoolantibes, 170 Chemin des terriers, 06600 Antibes, France in October 2021 as part of Festival Coul’Heures d’Automne @coulheuresdautomne and @unwhite_it. Photos taken October 2021.

Thanks @mephistodesign for answering my questions: “No it's not wrong, it's flawless. Chaos, well it's the ambient Chaos that is well materialized in the Squid Games TV series.
It's acrylic spray paint.
Thank you”
