To us, play is a style of engaging with the world, a process of testing the
boundaries and experimenting with new possibilities. We see tinkering as
a playful style of designing and making, where you constantly experiment,
explore, and try out new ideas in the process of creating something.
Tinkering can be hard work, and sometimes it might not seem like play.
But there is always a playful spirit underlying the tinkering process.
