## What is TempusLocusLux?

This app is not a clock that continuously displays time as numbers.
Time generates a field of light, which is rendered across the entire screen.

The light you see is not decorative.
It is the structure generated from time itself.
This app allows you to experience that very transformation as “time.”

The design of the app is based on three concepts:
• Tempus (time)
• Locus (space & place)
• Lux (light)

Time is not something to be displayed; it is the origin from which a field emerges.
From time, position is determined.
From position, light appears.
The field of light is in constant transformation, and no configuration ever repeats exactly.
It is a “clock” that exists only in that singular moment.

The date is not shown directly.
However, the spatial arrangement of the minutes is determined by the current year, month, and day.

This design expresses the irreversibility of time.
Even if the same minute and the same hour occur, a different date will never reproduce the same structure.

The field forms according to the unique conditions of that day.
There is no return to the past.

Time is mapped into space, and space is visualized as light.
This app is not a device for reading time.
It is a device for experiencing the field generated from time.

The structure forming at this very moment exists only at this exact time.
That is the present of this clock.
