How to make solder less breadboards neater and tidier when prototyping
that is amazingly cute

Am I missing something? If you're going to be soldering to make those, why bother with solderless breadboard? I thought people used the stuff to not have to solder....
“Am I missing something?”
These are solderless breadboard helpers.
Plug it into your solderless breadboard and you immediately have 10 LEDs ready to connect to your prototyping Arduino.
And yes, you make a few of them ahead of time so they are ready to go.
Brilliant !
Anyone selling these now ?

Have been for ages!
Can't seem to find the older version however. 
LED bargraphs exist, as do DIP resistor arrays, so its not difficult to have 8 LEDs with just two packages without having to solder anything.

Making boards for sub-circuits can make wiring easier.
This is the first scrolling LED matrix I breadboarded:
This is the second which I could do on a single breadboard:
