I built an interactive cosmic playground where you sculpt galaxies with your cursor, create supernovas with a click and type words that dissolve into stars
hey everyone, I built this as a side project because I wanted to see whats possible with a canvas element, vanilla JS and some particle physics.
here is what you can do:
* **Move your cursor** to trail glowing particles * **Click** to trigger a supernova burst (with screen shake) * **Hold the mouse** to create a gravity well that attracts nearby particles * **Right-click** to spawn a black hole with an accretion disk that devours particles * **Type anything** on your keyboard - your words appear and dissolve into hundreds of stars * **Capture button** saves your creation as a PNG
everything runs client-side in your browser. No sign-up, no tracking, no data collection. works on mobile too (tap and drag)
The whole thing starts with a Big Bang intro - click the seed and the universe explodes into existence.
