Signature Design Concept

The homepage of Ai Bestie will feature an interactive "Mood Wheel" that users can spin to select the AI bestie's mood. This wheel will be a vibrant, animated 3D element using @react-three/fiber and @react-three/drei, allowing users to click and drag to rotate it. Each segment of the wheel will represent a different mood, dynamically changing the background color and theme of the page to match the selected mood. As users hover over different moods, subtle animations and sound effects will enhance the interactive experience, making the selection process engaging and memorable.

Interaction Model & Motion Direction

The landing page will utilize a "parallax" interaction model, creating a sense of depth and engagement as users scroll. Layers of atmospheric elements will move at different speeds, providing a visually rich storytelling experience. Internal pages will adopt a "static" model to ensure clarity and ease of use, focusing on the chat interface and customization options.
