Every year on November 14, the diabetes community celebrates World Diabetes Day. The symbol for this specific day is a blue circle. To engage company employees I developed the following internal campaign: Each employee received a blue Lego brick that they could bring and stick to a wall. As a whole, the bricks formed a blue circle. To inform and mobilize the employees I created different types of communication vehicles. I was responsible for ideation and execution of the campaign, including running a photoshoot, designing all communication materials, and the actual Lego wall itself on World Diabetes Day.
