This is the beginning of a class of foxes with random processes.
The above process is a special form of a random walk on the plane.
We believe that this process is new! If you see something similar in literature, please let us know.
We believe that this process is new! If you see something similar in literature, please let us know.
"Uniformly selected" means that every direction has an equal chance of being selected.
In other words: direction ~ Uniform[0, 360].
Point O is the origin. Generation of point A is irrelevant since OA does not change whether there will be a triangle or not at the end of the process.
Also, it is not important but assume that the random directions are generated clock wise.
The answer has not been confirmed yet, let us know if you find something very different.

Red Fox: Hey Polar, check this out; a unique configuration of a circle and a square! Ain't it beautiful?
Polar Fox: Not bad! What'd you have to say about it?
Red Fox: Here I say all fractions are reachable by adding simple tangents and other similar connections.
Polar Fox: Hmmm! Is that not a too strong statement?
Red Fox: Well, imagine drawing new tangents and line segments between existing intersection points.
If you keep on doing that, soon those intersection points will numerically-explode. And you can compute any fraction similar to the answer.
Polar Fox: OK. There are infinitely-many integers but NONE satisfies: a-cube plus b-cube equals to c-cube. Do you have one such a, b, c?
Red Fox: I know Fermat says NO. And I see your point. But this is not the same thing. You can probably span the whole plane like this.
Polar Fox: Fine, give me an 11/19 then.
Red Fox: I got to work on that.

Does the above have any "haiku" value?

Even though material interests may drive the human behavior,
there are still worldly images and unworldly lyrics inspring novelty,
reminding them to do good.
How can you draw righteousness on a board?
Does it really matter if charity is concave or convex?

Polar Fox: Dude, did you get any permission to use a trademark?
Red Fox: What permission? This is a public service we are engaged in.
Polar Fox: Oh really? Still I say that logo has an owner. It says in its corner, see.
Red Fox: Go ahead; let those capitalist scumbags know about it.
Polar Fox: Oh come on Red, stop acting like a mild Chávesian socialist. You spent all your time in youtube and facebook.
Red Fox: Yeah, I am extending my base in the internet for a revolution.
Polar Fox: Yeah, sure. The only thing I see revolving is your chubby belly.
