I've just begun starting an entry for an exhibition type thread elsewhere, under the theme of music, but this should suffice in giving you the general idea of what i'm suggesting. I was thinking music players or instruments merged with people (this would include anything throughout history. From gramophones to ipods. Anything at all that fits under the theme.):
Eh, if it's already been done/suggested, forget i said anything.
This pic is really only a couple of rendered parts of pictures sitting on top of the original, with basically no editing to the main picture (so very little work on my part). It should look better when i've spent some time on it, but i wouldn't submit this one here if the idea was chosen.
