What is a line, natural inspiration within contemporary design.

I recently acquired this lovely package.  It's a collection of digital print test paper from the company GFSmith.  As interesting as the stock choices were, it was more the designs on the stock that caught my attention.  The design mirrors natural mountain and iceberg shapes, yet the colours do not.  I love the visual aspect and versatility of colour within the consistency of the design.  It is a visually engaging way to advertise stock, one that forces attention.

Here i've taken inspiration from the shape of this design and adapted it into my project.  It relates because it is similar to soundwaves- i find the shapes inspiring because of their flowing lines.
