I think designers are interested in doing good, meaningful design work, and some subset of designers are interested in/can afford to do unpaid volunteer design work, which could include open source projects if the project was pitched well and set up to accept design contributions: http://opensourcedesign.is/blogging_about/import-designers/
I am interested in UX and design opportunities within open source projects. Would be happy to talk, share my background, and see how I may be of service. tom [a] thegrif [dot] net :-)
