colophon

a note about the machine that prints the machine.

// PHILOSOPHY

this site is a love letter to the terminals i grew up reading about and the avionics displays i grew up watching. the goal isn't "retro for retro's sake" — it's signal density. amber phosphor survived for a reason: it respects your eyes, it respects your time, and it makes hierarchy visible.

// STACK
runtime   :: tanstack start v1 (react 19, vite 7)
deploy    :: cloudflare workers (edge)
backend   :: lovable cloud (supabase under the hood)
ai        :: lovable ai gateway → google/gemini-3-flash-preview
styling   :: tailwind v4 native @theme + oklch tokens
type      :: ibm plex mono, ascii everywhere
icons     :: none. text and box-drawing characters only.
// COLOR_TOKENS

// EFFECTS
  • scanlines — repeating linear-gradient at 3px intervals
  • flicker — subtle opacity dips on a 4s loop
  • vignette — radial darkening to mimic curved glass
  • power-on — vertical scale flash on every route change
  • phosphor glow — text-shadow tuned per theme
// CREDITS
  • ▸ inspiration: vt220, ibm 5151, the cathode ray tube manifesto
  • ▸ ascii cow: original cowsay by tony monroe (1999)
  • ▸ weather: open-meteo (no api key, free, lovely)
  • ▸ built with assistance from lovable ai
