The Fantasy Workshop aimed to stimulate the multi-sensory perception through building games. We worked with a class of fourth grade chidren from the Visually Impaired Secondary School. Together, we built a 3d model of a city out of Lego bricks. They each had to create their own neighbourhood, to decide what functions they need and how they work together as a whole. Our purpose was to improve their orientation skills by helping them understand the scale notion and how to change perspectives, from a small scale to real size space.
