Why does the binomial distribution approximate a Gaussian?

Welcome to PF.

Yes, it is a coincidence.
It looks like moisture is wicking through the render, with a mould or algae growing there.
Is this the cool, shaded side of the building?
What city?

Nearly every natural relationship between variables (within some arbitrary range) either looks linear, quadratic, exponential, sinusoidal or gaussian. Change the scales of the x and y axes an you can get a 'convincing fit' (good enough, often to convince a jury).
Don't blame the Scientist who starts off with one of those curves when trying to work out the theory; it's always a good first step.

I made a habit out of annoying my experimentalist friends by asking them "Is that a Gaussian?!" every time they were looking at data.

It's not a Gaussian. Too pointy.

I once saw a Gaussian when snowflakes leaked through a slot onto a narrow ledge.

Too kurtotic to be Gaussian
