I happened across this site for a Responsive Web Design Workshop at Miami University next month:
http://buildresponsively.com/
Unfortunatley I won't be able to go, but thought I'd pass it along to see if anyone else was interested. Also of note, at the bottom right of the home page is a Twitter vote for which cities get to host another and Columbus is on the list. It would be nice to see Central Ohio get to host it.
