Made up font
After photographing the random shapes which formed letters, I took the images into illustrator and formed a font from them. Some nice shapes in the end- although they dont all come together as a single font, there are some good letters which could act as starting points for full fonts.
Here is an example of the font in use. The photo used is a stock image called ‘Storm at Sea’ by Arwenarts, taken from Deviantart.com
