After a field trip to Lego House in Billund, Denmark, I chose their physical outdoor zone because I am interested in outdoor play, and also Lego house's outdoor zone was under development.

In Billund, the rain and wind are very common. I want to design a play experience that turns the negative weather to positivity and implicitly teaches children shift the way of thinking.

After discussion with designers from Lego House and Lego Foudndation, I decided on the wind concept because of its uniqueness and better expected playful learning outcome. The children are expected to be "I am enthusiastic about trying this again", "I am invested", "I am deliberate about the changes i make", "I am developing my own understanding" and "I cooperate with others to initiate new play experience".

Playful tension is a theoretical concept of play design, developed by Jess Uhre Rahbek, that bridges the gap between play theory and play design practice. To assist the player in achieving playful tension, the play needs to bring the orderly and the unruly together.

It is impossible to develop the whole play experience within the time frame. So I focused on developing a hang glider because the flying is the key part of the experience.

I tested various times both indoor and outdoor.

At the end of the project, I presented my prototype to 10 designers from Lego House and Lego Foundation and received feedbacks from different perspectives, like business feasibility, local legislation, design process, space management and etc.
