TITLE: Creativity and the mechanization of elementary geometry
QUESTION [8 upvotes]: In plane geometry, it is customary to say that checking proofs 
is a mechanical process but that finding new theorems
is a creative activity.
Citing J. Hadamard, "logic only sanctions the conquests of intuition."
We have now computer programs that can check the correctness
of geometric statements (at least first order statements)
and interactive geometry softwares are used routinely
in geometry classes to teach elementary geometry. We can use these programs to discover new theorems, 
but is there any program that is able to find new geometric 
statements on its own? More precisely, 

Is there any new and interesting result in plane geometry that has
  been produced by a computer program without any human intervention?

The answer may state such a result together with the relevant
reference.
Of course, the software is always made by humans,
but the result output by the machine should not be 
known prior to the start of the program and no intervention
should happen during the execution of the program.
Also, new and interesting is subjective.
By new, I mean some result that is not an easy corollary
of some theorem prior to the XXIe century. 
By interesting, probably the real test would be to produce
several results sufficiently different from each others to show creativity and fit the taste of the many geometers on mathoverflow.

REPLY [5 votes]: A new theorem discovered by computer prover (1989)

Concerning Pappus lines and Leisenring lines there exists a set of
  interesting theorems. Here we show that these theorems can be easily
  proved by our computer prover which is implemented on the basis of
  Wu's method for mechanical theorem proving in geometries. Using this
  prover we discovered, furthermore, a new theorem: The six intersection
  points of every Pappus line and its corresponding Leisenring line are
  collinear.
