I suppose there are a couple things to talk about here. First of all, Duet is a soon to be launched iPhone app, which from what I can gather, is some sort of intimate social network where can do ‘stuff’ with other people. Perhaps ‘Duet’ is a some sort of pun on ‘Do It’? And judging from some of the talent assembled, I’m sure it will be a well designed and executed app. As far as the site, it’s also really well done. The design of the logo takes the theme of ‘duet’ somewhat literally, with twin lines comprising the letterforms. The same concept is smartly carried through the icons down the page. All in all, this site does a good job of teasing what looks to be an interesting app.
