The design is minimalist and geometric, focusing on a circular base with a triangular cut-out section. This creates a clean, straightforward aesthetic that can be expanded creatively.

1. Take your cardboard piece into a dark room and use a flashlight to shine through the triangular cut-out. Observe how the light interacts with the edges and how shadows form around the piece.
2. The current design lends itself well to being turned into a spinning element. Attaching a small pivot point or axle at the center could turn it into a rotating dial. This could be used for interactive installations, like a selector or a decision-maker wheel.
3. Try experimenting with different textures or layers to enhance the design. For instance, covering the triangular cut-out with translucent colored paper can create interesting lighting effects if LEDs are used.
4. If you're leaning towards an educational theme, the piece could serve as a model to teach fractions, portions, or even as a visual representation of concepts like the phases of the moon.
