HOW?  Ask participants to build a collage from a provided collection of images, and to explain the significance of the images and arrangements they choose.

WHY?  This illustrates participants, understanding and perceptions of issues and helps them verbalise complex and unimagined themes.

(e.g.  Participants were asked to create a collage on the theme of sustainability to help the IDEO team understand how new technologies might be applied to better support peoples, perceptions.)
