Marek and I delivered a novel paper prototyping workshop together at the Arts Council of Wales Annual Conference. This technique, pioneered by Joel and Pete, challenged delegates  to design simple prototypes for a “creative future” smile detector application. There were 50 delegates, divided into 10 teams, with only 45 minutes to create a paper prototype for their concepts. All the teams rose to the occasion, and managed to explain their ideas in less than a minute, with smile powered cars, air travel (air smiles!) and charity collections, raising smiles all around.
