CHIME

An instrument made of glass.

Glass that rings when you touch it, and remembers what you played. The interface is the material.

The material

Struck glass settles slowly.

Every strike blooms into the surface and fades like phosphor. The pane below is live: hit it, then watch it let go.

A4 · 440.0 Hz
4 partials
1 / 2.32 / 4.25 / 6.63

A struck pane rings with four inharmonic partials, the ratios of real glass.

3.2 seconds
fundamental decay

The lowest partial holds longest; the bloom you see decays on the same clock.

0 easing in
the strike lands on your touch frame

Glass answers instantly, then takes seconds to let go.

The instrument

Five notes. No wrong ones.

Twelve panes, tuned to a pentatonic scale across two octaves and a step. Anything you play agrees with itself.

The memory

The glass keeps what you played.

Your last seven notes hold as lit layers, deepest first, each letting go on its own clock.

12 panes · 1 material

One glass grammar carries keys, chrome, and memory.

1 light source

Every surface takes its highlight from the same upper left.

It feels like this, and the whole page is one file.

CHIME

The glass remembers what you played.

If a product surface should feel like this, the same system builds it in any register.

One of four use cases of THE REGISTERS, in its liquid glass register. Designed and built as one page; the instrument is real, and so is the glass.
