The very idea of the conference is to bring together diverse fields and levels of experiences to exchange ideas about human-focused design.
I chose to represent diversity by color and the idea of the conference in the converging of the tapered ends of the comets/shapes. The broader ends of the shapes are representative of taking ideas from the conference to engage our world.
All the shapes come together to form an abstract star to represent the level of success and international renown the organizers hope the conference will achieve.
