Happy Clouds
28-year old London artist Stuart Semple has made lighter-than-air foam smiley faces using a flogo machine. A flogo machine, invented by two special effects inventors in the 1990s, uses glycerin, food dye, and helium, and extrudes the resulting mixture through a die to create floating logos. Semple has used this technology to release one pink-tinted happy face cloud every 7 seconds near the Tate Modern and Bankside walkway in London. The Happy Cloud installation is intended to be a message of hope and positivism in reaction to the gloom of current economic and natural disaster events. ‘I just wanted to make a piece of work that would cheer people up a bit.’ he continued saying, ‘I know at times like this it’s easy to make creativity a low priority, but i want to show that on a very human level an artistic idea might be able to do something important even for a fleeting moment. This was the most straight forward way I could think of to literally contribute something happy to the atmosphere.”

An audience gathers near the Tate Modern to watch the happy clouds float into the air.
