A little while ago, I shared a fun project here: the **Cosmic Odometer** a calculator that uses Earth's spin, solar orbit, and galactic drift to figure out exactly how many kilometers you've traveled through the universe since you were born.

**Here is what is brand new in V2:**

**Interactive 3D Solar System & Galactic Vortex:** I integrated a full Three.js engine. If you open the "Cinematic" mode, it calculates the Sun's linear movement through the Milky Way and generates a massive, dynamic 3D corkscrew trail. You can pan, zoom, and actually see the literal path we carve through space.

**Distance This Session:** A live, ticking tracker that shows exactly how far you've traveled through the cosmos just in the time you've had the website open. (Spoiler: We are moving *fast*).

**Travel Receipts:** You can now click the 🧾 icon to generate and download a sleek, retro-style PNG "Official Travel Log" of your personal cosmic mileage.

**Cosmic Connection (Multiplayer):** You can now enter a friend or partner's birth date. The engine will calculate the "Distance Gap" (how far Earth moved between your two birthdays) and exactly how many miles you've traveled *together* since you both existed.

**Privacy First:** Just like V1, absolutely zero data is sent to a server. All the heavy math and 3D rendering happens locally right inside your browser.

Thank you all so much for the initial love.

I’d love to know what you think of the new 3D cinematic vortex! and feedback would be much appriciated. Drop your total cosmic mileage (or share your travel receipt) below!
