'Twitter Ball'
562 reused plastic bottles, hundreds of LED lights and live Twitter feed are the ingredients for this Christmas holiday installation.
Working with design company Sennep, this giant tweet-reactive bauble, flashes different colours when selected words from Cohn&Wolfe's holiday message are tweeted.
Each time their entire message is retweeted they donate $1 to Project Kaisei, a non-profit organisation researching ways to reduce the Plastic Vortex - a patch of plastic the size of France and Germany combined, floating in the North Pacific.
