I’m in research mode for Sounds of Soldiers, but this article on DIY currencies came along of its own accord. Most of the currencies discussed in the article are virtual and tradeable by mobile phone. In the first draft of Sounds of Soldiers the Levenshulme based currency- the Levy- has been imagined as a tangible item, paper chits or coins. Perhaps it might work better as an electronic unit. I shall have to consider how it will best fit into my story’s world.
