I remember exactly two occasions where the Mandelbrot has been seen in meat-space.

One was a mention on Slashdot:
http://science.slashdot.org/comments.pl?sid=1444562&cid=30110928

"I found that hot chocolate (not too watered-down) in a white ceramic mug leaves a very rudimentary but easily discernible "Mandelbrot" set. At least the classic image (I have no way to zoom in to great detail on the side of my mug.). The set is left over from "chocolate bubbles"."

The second is in reference to magnetic fields from this page:
http://www.miqel.com/fractals_math_patterns/visual-math-mandelbrot-magic.html

"Also Mandelbrot curves have been discovered in cross-sections of magnetic field borders, implying there is a 3-D mandelbrot equivalent that is closely tied to electromagnetism and therefore a deep structural and fundamental aspect of life, and physical space/time."

Are there any others?

It would have been nice if they had supplied an image to go along with such a statement.  Especially since I have had many such cups over the last several decades and have yet to notice anything similar.

I think they just see the classic cardioid that can be seen due to reflexion of light on a cylindric surface. Look at your cup of chocolate (or coffee, or anything else...) under a strong light...

The cup of tea/coffeee/whatever is the typical exemple for explaining a cardioid  grin

often times... there are other approaches which are kinda crappy until you put them in the context of parallel machines

Lol, do you think that's all it is? cheesy I can't imagine how he'd mistake it for that, because all one would have to do is move the cup slightly and the cardioid pattern would change drastically.

Yes agreed. I asked him for a photo actually in my reply. No response.

I agree with your thoughts, concerning the light reflection.  Just never noticed it since I reside in a cave and only use the light from my monitor to see by (and rarely go out during the day).      wink

The set is left over from "chocolate bubbles".

I think (I hope?) he's just making a joke.  The Slashdot crowd is always full of wise guys.  I was a regular there for several years but kind of got bored with it.

If he's not joking, then I agree, he probably just saw an odd reflection.  Or, he's been staring at the M-set for too long (like me) and now every time he sees two circles touching each other, his brain tricks him into seeing the M-set.  smiley

Yeah, when I've been staring at the M-set for too long my brain tricks me into seeing it in shapes plainly not fractal at all - usually in the negative shapes formed by two or more objects.
