What is Gravity Dots?
Gravity Dots is an interactive digital hourglass, a playground where physics meets art. It simulates thousands of tiny, colorful particles falling under the influence of gravity, creating a mesmerizing cascade that you can control. Unlike a static image, this simulation is alive—reacting to your touch, bouncing off obstacles, and painting the screen with a dynamic flow of pastel hues. It's designed to be a visual sanctuary, a place where you can pause, watch, and let your mind drift along with the gentle stream of dots.
The Science of Physics in Your Hands
Gravity Dots uses Matter.js, a powerful 2D physics engine, to simulate realistic particle behavior. Every dot you see follows the same laws of physics that govern the real world—gravity, inertia, friction, and collision. When you draw a line, you're not just creating a visual obstacle; you're introducing a new physical constraint into the system. The particles respond instantly, bouncing, rolling, or pooling based on the angle and position of your drawings.
This isn't pre-recorded animation—it's real-time computation happening in your browser. Each particle has its own mass, velocity, and collision properties. This means no two sessions are ever exactly the same. The slight randomness in spawn positions and velocities ensures that even if you draw the same pattern twice, the flow will be subtly different. It's this combination of predictability and surprise that makes the simulation endlessly watchable.
How to Play
There are no scores to beat or levels to clear. Simply click and drag (or touch and swipe) anywhere on the screen to draw lines. These lines become solid obstacles for the falling dots. Watch as the stream diverts, pools, and cascades over your creations.
- Draw: Create ramps, cups, or complex mazes to guide the flow.
- Listen: Enjoy the subtle, rhythmic "thud" as particles collide with your lines (toggle sound with the speaker icon).
- Reset: Use the "Clear Lines" button to wipe your drawings or "Reset All" to start fresh.
When to Use Gravity Dots
Gravity Dots is perfect for moments when you need to reset your mind without complete disengagement. Use it during work breaks to give your eyes a rest from text-heavy screens. Open it in the background during focus sessions—the gentle stream and soft collision sounds create a non-intrusive ambient environment. It's also helpful before bed if you're someone who struggles with racing thoughts. The act of drawing and watching provides just enough mental engagement to quiet anxious thinking, without being so stimulating that it keeps you awake. Think of it as a visual fidget toy for the digital age.
Inspired by Zen Gardens and Sand Timers
The concept behind Gravity Dots draws from ancient tools of contemplation. Zen rock gardens invite you to arrange sand and stones, creating temporary patterns that shift with each session. Similarly, an hourglass offers a mesmerizing flow of sand—predictable yet hypnotic. Gravity Dots digitizes this experience, allowing you to shape and guide the flow with a simple touch.
Unlike physical objects, this simulation is infinitely reusable. There's no cleanup, no setup time, and no materials to replace. You can experiment boldly—create chaotic mazes, smooth ramps, or intricate funnels—and reset instantly. It's a playground for curiosity with zero consequences, making it ideal for those who find peace in creative, low-stakes exploration.

Why it Relaxes You
The human brain finds deep satisfaction in predictable yet complex patterns—a phenomenon often called "visual ASMR." The physics of Gravity Dots offers a perfect balance of order and chaos. You can predict that the dots will fall, but the exact path of each particle is unique. This engages your brain in a state of "soft fascination," allowing it to rest from the intense focus required by daily tasks. The act of drawing and seeing an immediate, physical response fosters a sense of agency and flow, helping to ground you in the present moment.
