LEGO Serious Play
Playful learning is going to be a very important people-centred design theme in the near future, and LEGO seems to have understood:

“LEGO Serious Play is an innovative, experiential process designed to enhance innovation and business performance. Based on research that shows that this kind of hands-on, minds-on learning produces a deeper, more meaningful understanding of the world and its possibilities, LEGO Serious Play is an efficient, practical and effective process that works for everyone within an organization.”

“LEGO Serious Play uses LEGO bricks and elements and a unique method where people are empowered to “think through their fingers” – unleashing insight, inspiration and imagination.”
