For three days during the gray month of November, Parisians were surprised with pop-up bubbles—greenhouses filled with hanging plants, seemingly appearing about of nowhere. Actually, these bubbles were the project of the Flower Council of Holland, and were designed by French designer Amaury Gallon, who is well known for his vertical gardens. Named Ma bulle, ma plante et moi (or My Bubble, My Plant and Me), the project was inspired by Andy Warhol's prophecy that everyone would have 15 minutes of fame.
