Create a black-and-white hypnotic rotating spiral.

Project Overview
Design a visual feature consisting of a rotating black-and-white spiral with a hypnotic effect. This spiral will be presented in constant motion to create an illusion of being drawn into the center, supported by ambient sound to facilitate hypnotic induction.

UI/UX Design and Flow
- The spiral should be prominently displayed on a neutral background to keep the viewer's attention focused on its hypnotic effect.
- Design the spiral with alternating black and white stripes that smoothly twist towards the center.
- Ensure the central part is more concentrated and the edges expand outward to emphasize the hypnotic draw.

Core Functionality and Logic
- The spiral should rotate clockwise at a steady speed of approximately 10-30 revolutions per minute.
- Movement must be smooth and continuous, without jerks or accelerations.
- The diameter of the spiral should be 500px to optimize the hypnotic perception.
- Integrate ambient sound: a soft, repeating tonal sound or ambient white noise that complements the hypnotic visual.

Best Practices
- Maintain uniform stripe width and gradual transitions between them to enhance the hypnotic effect.
- Ensure that the rotation speed is comfortable for the eyes while remaining effective.
- Provide seamless looping for both the visual spiral and sound to ensure constant hypnosis facilitation.
- Optimize the design for various screen sizes as necessary.

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. The optimal rotation speed of a hypnotic spiral is approximately 10-30 revolutions per minute. This speed creates smooth and continuous motion that is fast enough to produce a hypnotic effect, while remaining comfortable for the eyes. Consistent rotation without jerks or accelerations enhances the feeling of being drawn into the center of the spiral and allows the viewer to focus on its hypnotic impact.

Q: What dimensions should the spiral be?
A: For example, a diameter of 500px.

Q: What type of ambient sound are you looking for?
A: For example, a soft, repeating tonal sound or ambient white noise.
