CosmicX

I think this is the coolest personal project I've ever built.

Introducing CosmicX—an interactive space exploration experience with two connected modes.

Become the Creator lets you explore and control a living universe featuring planets, moons, galaxies, asteroids, comets, and black holes. Experiment with gravity, collisions, impacts, eclipses, and other real-time space simulations.

Before the Stars takes you on an interactive journey through the history of the universe, from the Big Bang to the distant future, across 11 major stages of cosmic evolution.

Highlights:

• Explore the Solar System, the Milky Way, Andromeda, and beyond.
• Six immersive camera modes.
• Real-time physics with collisions, craters, debris, and orbital changes.
• Interactive Big Bang timeline with cinematic controls and detailed astronomical information.

This has been one of the most challenging and rewarding personal projects I've ever created.
