A nice - and occasionally surprisingly poetic - website on
mimetoliths.
The idea to post it was inspired directly by the various threads about seemingly artificially made structures on Mars and elsewhere, but I thought a
wider audience could profit from its educational content (hence an independent thread).
Don't get me wrong: I am perfectly open to the idea that some of the formations discussed in the various threads, notably some of the formations on
Earth,
could have been manipulated by some force other than nature. But I am sure everyone will agree that being acutely aware of what nature
can do - and does - is not a bad idea.
I also think it would be a good idea for people to contribute as many natural anthropomorphic (or other interestingly shaped) rock formations from
their home countries, or places they have been to. This way, we could build a useful library of images, for reference and educational use.
