创建一个黑白催眠旋转螺旋。

## 项目概述
设计一个数字体验，展示一个黑白催眠旋转螺旋。该螺旋将产生引人入胜的催眠效果，旨在帮助放松或集中注意力。

## UI/UX设计与流程
螺旋的背景应保持中性且无干扰，以确保用户全神贯注于螺旋。螺旋本身应由交替的黑白条纹构成，并平滑地向中心扭转。界面应包含播放/暂停控制，用于控制环境声音和螺旋运动。

## 核心功能与逻辑
- 实现一个以适中速率顺时针旋转的螺旋，营造出向中心吸引的幻觉。
- 确保条纹宽度均匀，转换平滑以达到最佳的催眠效果。
- 嵌入柔和、平静的环境声音，如轻柔的海浪声或音乐，以增强催眠体验，该声音应实现无缝循环。

## 最佳实践
- 注重极简设计，避免任何分心元素。
- 使用高对比度，确保螺旋在视觉上明显突出。
- 确保所有过渡效果平滑，实现无缝催眠体验。
- 考虑为视力障碍用户提供辅助功能。

A black-and-white hypnotic rotating spiral, creating a hypnotic effect. The spiral consists of alternating black and white stripes, smoothly twisted towards the center. The spiral is in constant motion, rotating clockwise at a steady speed. The movement creates the illusion of being drawn into the center of the spiral. The background of the spiral is neutral, without any extra details, to focus attention on the hypnotic effect. The central part of the spiral is more concentrated, while the edges expand outward. The hypnotic effect is enhanced by the smooth rotation, uniform stripe width, and gradual transitions between them. Add a corresponding ambient sound to facilitate hypnotic induction.

Q: What should the ambient sound be like?
A: Soft, calming music or a gentle sound like waves yes

Q: What should be the speed and duration of the rotation?
A: A moderate speed with continuous motion yes
