The campaign has been devised to celebrate the people who make the world a beautiful place.
A colourful installation of giant balloons was unveiled beside the Thames on Saturday (18 June) with happy messages attached.
Londoners were invited to share messages with their loved on we-makehappy.com. These loved ones were then surprised with an event invitation encouraging them to pick up their message on the South Bank.
Agency Wonder helped to create the balloon installation on London's South Bank.
