So I decided I needed an identity for my scriptwriting work and maybe even extending it to other copywriting and consulting:
In Greek mythology the muses were the nine daughters of Mnemosyne and Zeus, each of whom presided over a different art or science. The idea of a muse as a "source of inspiration" flows from this. So MUSE will take the raw materials of an organisation, product, website, video idea etc and provide the "inspiration" - mostly the wordsmithing I'm guessing, but maybe also the consulting edge. It may go nowhere, but it would be a preferred way of doing the bi-vocational thing than taking another job.
