This is a three minute video of a Demos event at the Hayward Gallery as a part of the South Bank Centre's 100 ideas to change the world festival. Instead of hitching in one speaker with one idea to change the world, we hoped to get 100 people with 100 ideas and then to get them all to meet each other in a speed dating style excercise (hence the title). In the end London had its heaviest snow in a decade, but about 60 people still made it. This gives a rough flavour of what happened. You can also see the new Demos director Catherine Fieschi, in full flow.
