By some chance, are there 1200px wide templates out there for photoshop? Our company has been using your adapt.js library for a while and conjunction with 960.gs (btw Great work! We love it) .
We just have issues designing for it. Our designer is asking for a psd of this size.
If there isn't that exists we'd like to go ahead and create some and contribute back to your project.
There aren't any 1200px PSD's, since the focus of Adapt.js was the JS itself, and the CSS that ships as a demo can be considered throw-away. If you want to make some PSD's, that's fine by me.
