DhobyGhaut wall art

I saw this wall art at dhobyghaut MRT yesterday. This painting is really really artistic. I think the artist tried to make something different by painting an abstract picture using a wall as the canvas. Even though i do not know what the meaning of this painting is, I like it very much.

I wonder what the artist was trying to explain. Is it just a meaningless picture? or is it something like a puzzle? which means when we arrange it again, it will become a non-abstract picture. No one knows.
