Block Display

In Minecraft, a 'Block Display' is a powerful entity that allows map and data pack creators to showcase any block or item in the game as a 3D model. It's not a vanilla feature but introduced via a resource pack named 'Block Display'. This entity is similar to an armor stand, but instead of holding armor or items, it displays blocks or items. Block displays can be rotated, scaled, and positioned, and have custom names, tags, and NBT data. You can create and modify them using commands (like `/display`) or item frames. These displays are used for decoration, map making, or data pack creation, such as creating custom models, animations, signs, and statues. With block displays, creativity is nearly limitless. Additionally, there are Text Displays and Item Displays, for displaying texts and items respectively, which together form a powerful display entity system in Minecraft. These features became part of the vanilla game after version 1.19.4, and can be used without mods or custom resource packs.
