At TEDxDelft, Jongens van de Tekeningen made live visualizations of all speakers and performers at TEDxDelft, 5 October 2012.. This giant drawing was made on a 1,5 by 5 meter piece of paper and it sold afterwards; the money was donated to charity. During the day, the process was streamed live over the internet and everything was recorded. In this timelapse video, the whole day is captured in just 1,5 minutes.
