Personal Black Hole

Unleash a mesmerizing black hole, or even two, into any web page. With auto-off timers and a screensaver mode

Light bends around the horizon in real time, two black holes trace Keplerian orbits, and every merger ends in a mass-dependent ringdown. A must-have browser extension for fans of space and science fiction. 🚀 Quick Start: 1️⃣ Install Personal Black Hole 2️⃣ Open the website where you want to try it 3️⃣ Open Personal Black Hole from your browser's extensions toolbar 4️⃣ Choose a mode and configuration, or press Random (Dice button) 😎 Enjoy the view. Bring one of the universe's most fascinating phenomena directly into your browser. Personal Black Hole drifts across the page and warps nearby text, images, and interface elements as it passes. Choose Solo mode to unleash a single black hole that drifts freely across the page or smoothly follows your cursor. Switch to Binary mode to create a system of two independently configured black holes. Watch them orbit one another, distort the page together, generate gravitational-wave-inspired pulses, accelerate toward contact, merge, and settle through a mass-dependent ringdown. After the merger, continue with the resulting black hole in Solo mode or watch the remnant evaporate completely. Or let the extension take over on its own: turn on Screensaver and a black hole launches automatically after 1, 5, or 15 minutes without mouse or keyboard activity, then disappears the moment you come back. ✨ Features: - Solo and Binary black hole systems - Two independently configurable black holes in Binary mode - Three sizes: Tiny, Massive, and Supermassive - Smooth Drift and Follow Cursor movement modes in Solo - Three Drift speeds: Slow, Medium, and Fast - Solo auto-off timer: 1, 5, or 15 minutes - Merger timer: 30 seconds, 1 minute, 5 minutes, or 15 minutes - Two after-merger outcomes: Continue in Solo or Evaporate - Screensaver: off, or automatic start after 1, 5, or 15 minutes of inactivity - Solo, Binary, or Surprise Me for every screensaver session - Screensaver sessions run your saved setup or a freshly generated random configuration - Optional Light Ring and Chromatic Aberration visual effects - Random configuration generator for both Solo and Binary - Compact and easy-to-use popup controls 🌀 Physics & visuals - Gravitational lensing, eccentric orbital movement, and final plunge — all physics-inspired - A unique orbital scenario for every Binary launch - Gravitational-wave-inspired pulses during the approach and merger - Mass-dependent merger remnant - Smooth remnant drift after continuing in Solo - Size-dependent evaporation animation - Endless Binary orbits in Screensaver mode — the black holes keep circling instead of merging 🌌 Ways to use Personal Black Hole: - Have fun experimenting with different black hole sizes, movement modes, visual effects, speeds, timers, and Binary configurations - Take a short visual break between focused work sessions — use the Solo auto-off timer or watch the countdown to a Binary merger - Let the Screensaver turn your browser into a living cosmic display whenever you step away from your desk - Turn a web page into a striking dynamic backdrop for your monitor — especially when filming videos with the screen visible in the background - Surprise a friend or colleague by making a familiar web page bend around a black hole - Build an intuitive visual sense of gravitational-lensing-style distortion - Observe Kepler-like Binary motion and compare how different mass combinations affect the system - Capture your audience's attention during a presentation or screen-sharing session by launching a black hole on the page you are showing 🌐 Where It Works Best: - Wikipedia pages and long-form articles - Blogs, portfolios, and static landing pages - Astronomy and science-fiction websites - Image galleries and visually rich pages - Any mostly static page with plenty of text and images to distort ℹ️ Compatibility notes: - The extension works on most ordinary websites. It cannot run on browser-protected pages such as chrome:// pages or the Chrome Web Store, and some websites may impose additional restrictions. - Personal Black Hole works best on mostly static pages. Videos, animated canvases, rapidly changing dashboards, and other dynamic content may occasionally produce stale pixels, visual artifacts, or edge ghosting. - Switching between tabs while an effect is active may occasionally cause temporary visual glitches. If they persist, reload the affected tab. - After installing or updating the extension, reload any already-open web page before launching your first black hole. ⭐ If you enjoy it, a quick rating or review helps others find it. ☕ If you would like to support its development with a coffee, it is always appreciated: https://ko-fi.com/bersent
