Autscape is an autistic-led conference, organised annually in varying locations around England. Governed by a strict set of rules and regulations, Autscape is a social and spatial setup explicitly devised to accommodate the tendencies, sensitivities, and preferences of people on the autism spectrum. It is a design, in other words-as organisers and participants alike often profess-for an altogether autistic space. The uniqueness of the event, and consequently its value to anthropological theory, lies in the shared imagination of the setting by those who inhabit it as one in which neurotypical masks, otherwise worn daily in keeping with hegemonic society's expectation of conformity, can finally be removed. I introduce the concept of un-festival as a means of depicting this event, similar to festival in its goals of defiance and inversion, but different from-and in important ways, opposite to-festival in its style and architecture, in the dispositions it encourages and mobilises, and in its potential implications. The un-festival offers a powerful comment on this moment in history, whereby masks are no longer seen as an item that affords freedom, but as one that stifles it. While Autscape participants remain doubtful as to the actual effect of this event on neurotypical society, they do nevertheless express a desire that this project will have some longstanding effects. That once a space has been designed for autistic people that considers their specific needs and tendencies, autism may then finally cease to be interpreted through a neuro-normative prism and freed to be understood in autistic people's own terms. © 2022.
