Name any pick Hologram to gain the datapacks effects (will remove unbreaking on the tool that is renamed)

To create a block display: break any block that drops itself (and not an item)
To delete a block display: hold the Hologram pickaxe and shift while looking at the block display to delete (let go to trigger the delete)
To rotate SOME block displays: hold the Hologram pickaxe, shift while looking at the block display, and after the outline appears deselect the pickaxe to trigger the rotation
