I'm thinking of it as a row of clocks, as roughly laid out where the red 
lines in the attached picture are.  An "office toy" (in my telework 
office adopted from my daughter) but also convenient. Yeah, no problem 
finding apps that can display it on the screen... I'm thinking more 
"art" or "furniture".   Shelf edge display is interesting. When I was 
sitting gazing upon the shelf, I was thinking battery powered clock, and 
if it has NTP (or WWVB), all the better, to keep it set.
