In 2022, I introduced you to James Brown, the Weta Workshop graphics engineer whose hobby is building amazing displays. Now, he’s built a crystal ball filled with shimmering, spinning volumetric light — and of course he’s playing Doom on it.

But not just any Doom. Voxel Doom, where every dot of the game’s graphics lives in 3D space, just like the dots of the volumetric display he’s created.
