This data pack adds invisible item frames and glow item frames to the game.
Examples of how it looks can be found in the images above.

Obtaining:
- Drop any type of invisibility potion on regular item frames in the form of items. It will give you as many invisible item frames as there are laying on the ground. The same principle applies to glow item frames.
- Throw a splash or a lingering potion of invisibility on already placed item frames.

How to remove the invisibility effect?
- Throw an anti-invisibility potion on placed invisible item frames.

How to obtain the anti-invisibility potion?
- Drop a splash potion of invisibility on a fermented spider eye in the form of items.

To be fixed [08/15/23 update]:
- Optimize function commands.
- Make invisible item frames spawn in structure chests.
- Add advancements for using the new items.
- Add lingering anti-invisibility potions.
- Make this datapack compatible with 1.17, 1.18 and 1.20.
- Add an item that highlights invisible item frames when held by the player.
