   7MinuteTimer.com — Design System
   Concept: the instrument panel. Every timer is a small machine —
   a dial, a row of ticks, a digital readout. The site borrows
   that vocabulary: ink-dark housings, brass tick marks, an amber
   needle/accent, and tabular mono digits wherever a number is
   doing real work.
