PlaceableSpeech - Text in Minecraft World
With the PlaceableSpeech mod, you can place text messages directly in the Minecraft game world. The mod adds two special blocks that allow text to be displayed in different ways.
One block is activated by simply pressing a button, while the second responds to redstone signals, opening up possibilities for creating complex mechanisms and interactive constructions.

Important Information
When using some shaders, a visual glitch may occur where text does not appear in the world. This is a known issue that is being worked on.
Before installing this or any other mod, be sure to create backup copies of your worlds. This will help avoid losing progress in case of problems.
