Cool project, but I also noticed the weird choice of #:~$ as a prompt, it uses almost half the width of the clock screen. And isn't # normally used to denote root shells? I don't think I ever saw it together with $.
My favorite prompt is >: as a callback to the Swan computer in the TV show Lost (not sure if it's also used in early Apple computers).
A prompt including > can be dangerous since that character also does shell output redirection. A sloppy copy/paste could, in theory, overwrite an important file.
The usually trick here is to use a unicode character like ⟫ (U+27EB) instead, which looks basically the same, but isn't interpreted as a redirection by the shell
