Artist Stuart Semple "just wanted to make a piece of work that would cheer people up a bit." The Happy Cloud installation filled the air outside the Tate Modern gallery in London. The faces were made from helium, soap and vegetable dye. He used a modified snow machine that Hollywood use for special effects to pump his pink faces into the grey sky. Visitors along London’s Southbank seemed intrigued by the creations and children ran after the pink clouds. Although the happy faces were short-lived - each of them lasting only around 30 minutes before dissipating. [via mcnitt]
