Room IV / Frequency
Lissajous Clock
Exact local time
Hours and minutes become two frequencies drawing one continuous knot. A bright pulse travels along the path once each minute.
Construction
The gold horizontal axis carries the hour frequency. The magenta vertical axis carries the minute frequency. Their ratio and phase determine every crossing.
How to read it
Each minute has a different knot. The bright gold point shows the current second's place along the continuous path.
The equation
The display states the active frequency ratio. The phase comes from the minute, keeping repeated ratios visually distinct.
