An immense video cube overlooks the field where the Nanterre basketball players are training this Tuesday afternoon. On a metal walkway, located 40 m high, the players look like Playmobil.

This cube, which replaces two of last year's giant screens, is one of the new features awaiting, this Wednesday, February 28 (8 p.m.), spectators of the event match of nanterre in the immense La Défense performance hall. The day before, while dozens of employees were busy transforming the usual den of Racing rugby players into a basketball hall, those from the specialized company CO2 Event meticulously posed, one by one, the 560 LED plates.
