I would have loved to have gone to the Serious Play conference, but seem to remember it cost serious money too. This talk from Tim Brown of IDEO sums up a great deal of my own thinking and research, although he got there first of course!

It’s much, much harder to put into practice than people think. Undoing the sense of embarrassment adults feel and the guilt that we’re “not working” is surprisingly difficult, even in design studios.

(Thanks to Karin for finding this for me).
