Pick a good background, it says a lot about you, nothing cheesy but definitely neat and appropriate. Watch what you wear, again nothing over the top but a polo would work. Also, minimize any chance of being disturbed, i.e. other people or phones. I know basing anything on image is dumb, but if they didn't want to gauge your mannerisms and how you present yourself the interview would be over the phone and not via skype.

More like want to see how you think one-on-one, not with several hours to craft an email response. But no sense showing up in nothing but a tie and a nipple ring while sitting on a toilet; no one is going to be offended by a polo shirt.
