Infinite Whirlpool Illusion
A mesmerizing particle simulation that creates a recursive, sinking sensation.
🧐 What do you see?▼
Hundreds of glowing particles orbit and accelerate toward a central black hole. The density of particles and their changing speed create a fluid, whirlpool-like appearance. The outer particles move slowly, while the inner ones 'zip' into the center.
🧠 Why this works▼
This illusion combines Centripetal Motion with Kinetic Depth Cues. As particles move closer to the center, they are programmed to increase in angular velocity—mimicking the real physics of a vortex (Conservation of Angular Momentum).
The brain uses this speed gradient to infer 3D depth. Even though the screen is flat, you perceive a "funnel" shape because the faster central movement suggests a steeper decline or a closer proximity to a 'drain'.
🧪 Try variations▼
- High Intensity: Makes the particles larger and more 'blob-like', changing the feel from water to something more viscous like lava.
- Switch Direction: Reverses the flow. Does it look like it's exploding outward now, or just spinning differently?
❓ FAQ▼
Are the particles pre-rendered?
No. Each particle is calculated in real-time using a 2D canvas API, allowing for the interactive speed and direction shifts you experience.
