Craig,
I agree, familiarity to real world objects hooks into what folk understand and are familiar with, in the modern studio there are opportunities to question the fitness of purpose of those designs. However, the visual language (form shape etc.) is far easier to translate for folk in the virtual world when it emulates the real world, for now it is what it is.
Out of curiosity, did the other company give you any feedback on your proposal or just side step it ?
From my experiences of life, folk can be pretty intransigent and any notion of change or new concepts are quickly put in the round filing cabinet.
The rebel in me says...
Yeah it's the vintage look, it's this designer image fashionable mixed up turn on tune in Tik Tok dance mode we live in now. Maybe when we get to the Minority Report level of computer music a new paradigm for music will exist way beyond our imagination.
M8. Hope your editing of the book gets easier as time moves on.
All the best of regards.
