Evelina Children’s Hospital: DeFrosty

A new interactive installation in London's Old Street is encouraging passers-by to keep the spirit of Christmas alive and focus on all the good feeling in the world. Featuring DeFrosty, a real snowman complete with scarf and carrot nose, the display is situated in the shop window of Old Street-based agency BBD Perfect Storm. DeFrosty is positioned in his very own freezer cabinet to prevent him from melting. The cabinet’s power is dependent on people tweeting using the hashtag #KeepDeFrostyAlive to stop DeFrosty melting away. Each tweet provides ten minutes of power to preserve DeFrosty’s smiling features. BBD Perfect Storm will spread further goodwill by donating 10p to Evelina Children’s Hospital for every tweet.
