Meet beside the bronze statue of Isaac Newton inside the courtyard of the British Library, Euston Road, London.
The Event Organiser will have a number of trackables which would like to go travelling around the world.
So bring any that you might have and are able to swop...discoverable trackables welcome too.
Event will run from 10am to 10.15am..so effectively a flash mob which allows you to get on with the day then!
