Hearty Hot Springs

This simple mod adds hot springs and hot spring stones to minecraft. Hot spring stones generate naturally in pools of water within cold biomes. When placed in water they force the emission of various smoke particles, stacking depending on the amount of stones in the water. 

The blocks themselves do not emit the steam, instead they make the water above do so.

When sitting in a hot spring, you gain the toasty effect, regenerating your health as you sit.

Finally, these blocks can be picked up and transported to create your own hot springs.
