This datapack adds hologram items you can craft! When placed, it creates floating text. Make the hologram item in a crafting table then use an anvil to change the text. Shift right click the text to remove it. It works in 1.16 and 1.17. In 1.17 you can craft them with glow ink sacs giving more use to glow squids. The resource pack isn't needed, but without it the holograms just look like spawn eggs. Leave a diamond and heart if you enjoy!
