I’ll be presenting this week, Thursday, June 28th at the JavascriptMN meetup. You can get the the registration details here - http://www.meetup.com/JavaScriptMN/
I’ll show some stuff that is nothing but basic HTML/css/javascript, then throw in some jQuery and jsRender, then move on to full blown WinJS-derived apps. We’ll cover as much ground as we can in the time available.
