250 members of the Art of Displacement are gathered this weekend, in Essonne. This discipline was popularized in 2001 thanks to the film "Yamakasi" "It's a practice with mutual aid and sharing," confirms François Terrien, the director of the ADD Academy of Evry.

Classes start from the age of 4 and we have adults who are up to 50-55 years old, says Terrien. "It can be dangerous if it's done poorly, but we're not daredevils," he adds.
