Core of the piece was the live production of a commercial together with the audience.What was advertised was somehting that actually can or must not been sold: Luck and happiness. Therefore, the audience is excessively animated to act frenetically excited and joyful. Three of them will finally get to perform in front of the camera, insisting on how much the sold product helped them to become lucky. A product named clover, a product that manifests through its own invisibility. Happy.go.lucky.
