This mod lets you place letters A to Z and numbers 0-9 on every type of wall. The crafting recipes are based on Braille:
Screenshot from the german Wikipedia-article about Braille, "oder" means "or"!
Instead of the "dots", you have to use "neontubes", which can be crafted with:

Then you just need to place the neontubes in the first two columns of the crafting grid, like the dots are placed on the screenshot.
When you need to craft the numbers, you need to place the tubes just like on the screenshot, but this time with glass in lower right corner of the crafting grid! This is because Braille uses the same Arrangement for the numbers as for the letters.
