An Ant

An ant is a block introduced in Java Edition 20w14∞ that moves around when placed on top of black or white concrete.

Obtaining
An ant cannot be obtained as an item even by using the command. An ant can be placed using commands such as or, and naturally generates in the "ant" dimension. It cannot be destroyed by tools or explosions.

Natural generation
One ant block naturally generates in the "ant" dimension, where it begins moving immediately.

Usage
An ant simulates Langton's ant. If placed on top of black or white concrete, it will move in a deterministic pattern, turning the concrete underneath it into its other variation. The ant block is the Turing machine mentioned in the update's changelog.

If two ant blocks collide, they will merge into one. It cannot be pushed by pistons, and is blast resistant, and can break bedrock.
