The Red Hearts (Les Rouges Coeurs) by Mademoiselle Paillette set the hearts of visitors to Gardens by the Bay's Supertree Grove thumping yesterday, with their pulsating action on stilts, as they kicked off this year's Voilah french festival. Organised by the French Embassy in Singapore and the Institut Francais Singapour, Voilah runs until May 21, and has more than 40 programmes, spanning arts and culture, gastronomy and science.
