This maneuvre is one of the hardest, most technical, and most dangerous of acrobatic paragliding. The pilot's wing is shooting so fast in front of the pilot that it's doing a complete revolution, bringing the pilot upside down above his wing. Wrongly executed the pilot could fall in his wing, with lethal consequences... its called infinit tumbling because the pilot is actually fueling the revolution with very precise skills to keep on doing it over and over.
to take this shot i was flying in a tandem paraglider, beside the pilot.
