About Window Constellation

Window Constellation is a free browser toy that turns your screen into an interactive artwork. Open this page in multiple windows positioned anywhere on your desktop, and glowing strands will connect each one together in real time. The result is a luminous constellation created entirely by your window positions, giving you a unique visual representation of how you've arranged your browser windows.

A small creature crawls along the glowing strands that form your window constellation, traversing from window to window. This playful element brings the browser window physics to life, moving realistically based on the spatial relationships between your open windows. The result is a mesmerizing combination of visual art and interactive animation that's purely designed for creative play and exploration.

Window Constellation runs entirely in your browser with no installation or signup required. Every aspect of this screen position art experience happens locally on your device—the strands, the creature, and the calculations all occur client-side, so your data never leaves your computer. It's a completely free toy for anyone curious about transforming their desktop into something visually unique.
