With very little plan of what to do with these boards I primed them with water and acrylic, once they had dried I saw the natural movement of the wood. I then decided to record these natural markings with the similar colours of Smiths map. And then as a contrast piece did a tonal study also mapping the lines of the wood board.
I think that the are only successful as a pair and really enjoy looking at them but am aware that I am required to take this idea forward. One possibility is to look at mri scans of humans or insides of animals, as this also might be deemed to have more value, by some, than a piece of wood.
