Nixie Tube Display

Nixie tubes are cold-cathode neon display devices that lit up calculators, frequency counters, and lab instruments from the 1950s through the 1970s, before LEDs and LCDs displaced them. Each glass vacuum tube stacks shaped metal numerals that glow a warm reddish-orange discharge near 640nm. This system rebuilds that look in the browser: glowing orange digits floating in depth on a near-black anodized chassis, never on cream.

辉光管（Nixie tube）是一种冷阴极氖气显示器件，从 1950 年代到 1970 年代广泛 用于计算器、频率计和实验仪表，直到 LED 与 LCD 将它取代。每根透明玻璃真空管里 层叠着金属数字阴极，通电后会泛起约 640 纳米的暖橙色氖气辉光。

这套系统把那种质感搬进浏览器：橙色数字带着景深漂浮在近乎纯黑的阳极氧化机箱上， 玻璃管面有反光与高光，绝不出现在奶油色背景里。它属于 Burroughs 公司命名、 Haydu 兄弟制造的那个仪表年代，冷峻、精密、带着真空管特有的温度。
