The Brainstorm Disk Drop symbolizes the process of brainstorming in the NuVu design process. It features a pegboard where users can rearrange obstacles, each representing a design challenge. These obstacles guide the disk along unpredictable paths, mirroring the iterative nature of brainstorming. The board stands at a comfortable height, making it easy for users to adjust obstacles, place the disk at the top, and retrieve it at the bottom.
