Running horse

This photo or more likely the content of it happened by accident. I told my friend to make bubbles with his Sprite and voilà there we had a running horse.

The question that pops up in my head is: " How many things happen not on purpose and happen to turn out as the coolest, nicest and most wonderful things on earth?"

Also does a running horse have a special connotation to it? Or a special meaning?

If you know the answer let me know...
