Happy to announce my shell version of a tix alike clock, named: novies (https://codeberg.org/oxo/tool/src/branch/main/novies).
Lights are customizable in shape, color and their update frequency. A horizontal as well as vertical version can be selected. It is configured for alacritty, but shouldn't be an issue to run in any shell. Not tested though.
I am currently working on configuration options as command line flags and configuration files, to be able to more easily change settings.
