The Maneki Neko (Lucky Cat, Money Cat) is a common Japanese figurine which is believed to bring luck, attract customers and bring prosperity. The Lucky Cat waves with the raised left paw and holds a historic coin in front of itself with the right one. Luck is associated here with monetary and material prosperity. The material element of the installation »The Global Pursuit of Happiness, or: The Army of Luck« by Boris Petrovsky is the »Lucky Cats’ Matrix«. It contains 520 shiny golden XXL Lucky Cats made of plastics. The visitors are requested imaginarily by the cats to interact as users: “Your concept of happiness is our lucky command. Write it on the keyboard”. Words and sentences can be put in and are displayed clearly visible with the paws letter by letter as sliding text marquee.
