Commissioned by Ogilvy Amsterdam, Refunk created the Dove Hello Sunshine campaign website. Aimed at a younger women demographic this message board was created to start a send-to-a-friend-to-a-friend chain, while politely collecting contact data (with opt-in) while offering a discount after posting 3 messages.

After receiving a message from a (girl)friend, you can send your own message via the rays of the sun.

UPDATE
The sun is now holding over 70.000 messages posted over a period of 2 months.
