Tunable analog behavior
Glow, beam decay, grid intensity, curvature, and contrast are exposed as controls.
CRT terminal simulator
Cathodium
A terminal that feels like recovered hardware without losing the utility of a real tool.
Project story
Why it exists.
Cathodium treats the terminal as an instrument. Glow, decay, scanlines, curvature, grid behavior, and contrast are part of the interaction model, not wallpaper.
The updated screenshot choice uses the stronger dashboard state instead of the sparse hero capture, so the project reads as functioning software.
The work pairs shader craft with practical UI decisions, which keeps the nostalgia disciplined.
Direction
How the idea becomes usable.
Believable desktop shell
The chrome, settings, and terminal surface give the prototype product weight.
Nostalgia with restraint
The look borrows from old hardware, then pares it back into a focused tool surface.

Hosting Path
The public preview can ship as a static web build on Vercel, Netlify, or Cloudflare Pages. Heavier runtime assets should be compressed, cached, and lazy-loaded so the experience still feels instant.
