How to Use Gravity Dots

Click "Start Simulation" and watch thousands of colorful dots fall from the top of the screen. They cascade downward like sand in a digital hourglass, bouncing and rolling with realistic physics. The magic happens when you draw: click and drag (or touch and slide on mobile) to create white lines across the canvas. These lines become solid obstacles that redirect the falling dots, creating new patterns and flows. Draw a funnel to collect them, or create angled ramps to send them flying sideways. Each collision makes a subtle sound—gentle pops and thuds that turn your drawing into a kind of procedural music. Use the trash icon to clear your lines and start fresh, or the reset button to clear all the dots and watch them accumulate again from scratch. There's no goal, no timer, no winning or losing—just the mesmerizing rhythm of dots flowing over whatever paths you create for them.

Why I Built This

I made this after one of those mornings where everything fell apart before 7 AM. I'd planned a perfect day—color-coded calendar, optimized schedule, the works—and then spilled coffee all over my laptop at 6:30. As I watched the liquid spread across my keyboard in unpredictable patterns, bouncing off keys and pooling in weird spots, I realized I was watching physics do its thing: gravity, surface tension, chaos. It was oddly beautiful, even as it was ruining my morning. I wrote about that day in When Your Perfect Day Falls Apart.

This simulation tries to capture that same feeling—watching small things follow simple rules and create complex, unpredictable beauty. The falling dots aren't random; they're following physics. But the patterns they make when they hit your drawn obstacles? Those are impossible to predict and different every time. It became a kind of visual reminder that letting go of control doesn't mean chaos—it just means watching what happens when you set things in motion and see where they land. It's just a digital hourglass for those moments when you need to watch something flow and remember that plans can ricochet in beautiful directions.

Tips for the Best Experience

  • Start by drawing a simple funnel at the bottom—watching the dots collect and spill over is oddly satisfying.
  • Try angled ramps to send dots flying sideways—the physics engine makes them bounce and roll realistically.
  • Draw slowly to create smoother obstacles—fast strokes can make jagged lines that create unexpected ricochets.
  • Use headphones to hear the subtle collision sounds—each impact creates procedural audio that changes with velocity.
  • Clear everything and just watch the dots pile up for a while—sometimes the best part is seeing the natural accumulation.
  • There's no right way to use this. If drawing lines and watching dots fall doesn't scratch that particular itch today, that's completely fine. Close it and try something else. No pressure—this is just one small tool for one specific kind of moment.
