Glacies
“ice”
coolcleanquiet
Flat planes of cut ice stacked in two corners of a cool grey page.
If you like Nord, you will feel at home here.
Flat faceted planes of pale ice in two opposite corners of a blue grey page. Held still, as it is while you read.
The plate
A calm page the color of cold air, blue grey by night and a frosty off white by day. In the top left and bottom right corners, large flat facets of ice lean on each other like the planes of a cut crystal, a few close tones apart, edged with hairlines. While Claude works a slow sheen of light crosses the facets, one plane at a time. When the answer is ready the light holds where it is.
While Claude works
The spinner takes one of these words in place of “Working”. When the app names the step it is on, that name stays.
- Cooling
- Settling
- Clearing
- Freezing over
- Holding still
After a turn of 20 seconds or more, Glacies plays a soft chime under a second and a half long.
With /tessera music, a quiet loop of its own plays while Claude works and stops when the answer is ready. It is off until you ask for it.

/tessera still stops the motion. Sound has three levels: /tessera quiet is silence,
/tessera sound is a chime after long turns (the default), and /tessera music adds the room's own
quiet loop while Claude works. Your choices are kept across sessions.
Only Glacies
Each plate also installs by its own name, and its commands use that name, such as /glacies still or /glacies music.
/plugin install glacies --marketplace btahir/tessera Where it shows
Themes appear in the Claude Code desktop and mobile apps. The terminal keeps its own colors. The chime plays on macOS only.
