People will be surprised to know that we have strongly discouraged the use of computers during the Summer School. Instead, we urged students to find other ways to communicate their ideas, mainly through hand drawing, but also through oral explanations. We find that students are incredibly resourceful when encouraged to use alternative ways of expression. Their hand drawing skills helped them communicate complex ideas visually and to spatialise relationships quickly, effectively and with great artistic expression, like some of the examples shown below . Computers were only used at the very end, to produce the final posters.
