Traveled to Thailand recently ans saw this Buddha's head in a bhodi tree at the ancient capital. The story is that when the old temple was sacked all the heads from the Buddha statues were cut off but this one was too heavy too take so was left under the bhodi tree where the roots are now growing over it.
I realise its not from nature but thought I would share, might be an interesting concept for someone to recreate in a bonsai.
