If you search for "HPDL-1414" you will find lots of suppliers who will happily sell you as many end-to-end stackable 4-digit LED bubble displays as you like :-) "Smart alphanumeric" even! Not as cheap as they used to be, but still starting from under 3$/Euros a piece on Aliexpress.

One problem with these is that they draw up to 70mA each. At 15 displays, that's over an amp.

I'd lay bets if the bubble LEDs were still available, they would be selling for all sorts of projects.
