Hidden maths on art

This is pretty cool. Previously, it was noted that Van Gogh used subtle maths in his paintings (link is in the attached article). 

But now, researchers add finding that Mondrian and da Vinci also used mathematics in their art. 

In da Vincis case, it's not a huge surprise since his interests extended well beyond art. He was a tinkerer and an engineer of sorts. 

But it's interesting to see how he used that in his art.
