Thanks to #ai I now have a pretty close palm DateBook reimplementation in #emacs displaying my agenda.org for me.

It is amazing to me how effortless this was created, I've duplicated most all features from originals various dialogs with little tweaks here and there. The target size is for my phones termux display with the keyboard showing for easy operation.

The original palm DateBook app for comparison. I have it running in cloudpilot fine on my phone, but I just can't give up on syncing my calendar across devices.
The tricky part was using the various block chars down to one 8:th char height and their color inverted pseudo chars to not only properly render correctly within the grid but also correctly redraw when the event is moved earlier or later in the day / week.
