Creator reconstructs 2D video into 4D spacetime visualization

Bilawal Sidhu demonstrated turning a geolocated 2D video into a 4D (space plus time) reconstruction by generating per-frame 3D Gaussians kept at their original spacetime positions. Using Opus 5.5, the entire journey's trajectory can be visualized all at once.
