Wow, that's interesting. It's a good start, and it would be interesting to see how the project develops.

From the video description:

“I wanted to build a city that feels alive, but is made entirely from ASCII characters.

This is a small custom engine built with JavaScript and Canvas — no Unity, Unreal, 3D models, textures, or shaders. The world is a grid-based city with roads, buildings, trees, cars, and pedestrians.

Every frame, the engine raycasts from the camera to work out perspective, depth, collisions, and what should be visible, then draws it all using letters, numbers, and symbols.

In other words: it’s a tiny 3D city made from blocks, viewed through a screen of ASCII characters.

Still a work in progress, but I’m going to keep pushing the atmosphere, detail, and interaction further.”
