Open Form is a gathering space in an open environment that invites participants to informal encounters. The installation takes the form of an inflatable torus that fluctuates based on the participation. Each person therefore has an effect on how others interact with the form, allows the participants to form relationships with one another, and brings spatial awareness. The goal is to complete as series of case studies as experiments to understand how public space can be used and what the intervention could be. This will be the second case study of the project.
