Particle Attractor Simulator - Online Gravity & Motion Art

A particle attractor simulator is an interactive physics-based art tool where hundreds of tiny particles move across a canvas, pulled by gravitational "attractor" points you place. The result is mesmerizing, flowing motion art that evolves in real time — perfect for creative visualization, stress relief, or exploring emergent patterns.

Simply click anywhere on the dark canvas to place an attractor. Drag existing attractors to reposition them. Double-click an attractor to remove it. Right-click (or tap on mobile) an attractor to toggle between attract mode (golden glow, pulls particles in) and repel mode (blue glow, pushes particles away). Use the preset buttons for quick multi-attractor layouts.

Choose from five visual themes: Aurora (cyan-green with subtle glow), Fire (warm oranges and reds), Nebula (purple-pink cosmic tones), Ocean (deep blue hues), and Rainbow (full-spectrum colors based on particle velocity — fast particles shine brighter). Each theme transforms the mood of your motion art.

Yes! Click the Export button (download icon) in the control bar to save the current canvas as a high-resolution PNG image. The exported image captures the full particle trails and attractor positions at that moment. Perfect for wallpapers, social media posts, or digital art collections.

The simulator uses an inverse-square gravitational model — each attractor exerts a force proportional to its strength divided by the square of the distance to each particle. This mirrors real-world gravity. A minimum distance threshold prevents infinite forces. Particles also feature velocity damping and canvas-edge bouncing for stable, beautiful orbits. The trail effect uses alpha-blended frame accumulation.

Absolutely! The tool is fully responsive and touch-optimized. On smartphones and tablets, you can tap to place attractors, drag to move them, double-tap to remove, and single-tap an existing attractor to toggle attract/repel mode. The control panel adapts to smaller screens, and particle count can be lowered for optimal performance on older devices.

Try these pro tips: ① Use 2-4 attractors for complex orbital patterns. ② Mix attract and repel types for dynamic tension. ③ Lower the Trail value (0.05-0.08) for long, sweeping motion tails. ④ Enable Auto-Rotate for hypnotic rotating patterns. ⑤ Experiment with the Ring or Scatter presets, then tweak attractor positions manually. ⑥ Reduce particle size to 1.5-2 for delicate, fine-lined art.

Attract mode (golden glow) pulls particles toward the attractor, creating orbital swirls and dense clusters. Repel mode (blue glow) pushes particles away, generating outward bursts and clearing zones around the repeller. Combining both creates fascinating push-pull dynamics where particles flow between attractors and avoid repellers — leading to intricate, organic-looking patterns.
