A-maze-ing Brain! is a giant brain-shaped maze co-created with children living with dementia and children with a range of abilities. The project was inspired by the maze-like brain architecture, the winding journey rare disease patients travel to receive a correct diagnosis, and the complex path researchers navigate in search of an effective treatment. Developed through the ArtPlay New Ideas Lab 2025 – 2026, an initiative of the City of Melbourne, the project’s first iteration embraced a deeply child-centred approach.  Children were not passive participants, but co-creators who actively shaped the experience and re-imagined the brain through curiosity, play and imagination.
