Eye of the Ancients

The Eye of the Ancients is a unique block featured in Botania. The block can sense animals in a 6 block radius, and shall output a redstone signal when a Redstone Comparator is placed next to the block. The counting starts at 2, so when there is 1 animal, it shall output a redstone signal with a strength of 2, when there are 2 animals, a redstone signal with 3 and so on.

When placed, an eye shall quickly and constantly appear on each of the four sides horizontally.
