The Omega 3.x Drupal 7 Base Theme is a highly configurable HTML5/960 grid base theme that uses built-in media queries to make the site responsive. Each zone (group of regions) can be configured for content-first layouts, that resize and rearrange themselves depending on the screen size of the user's device.
The presentation will walk-through the theory behind Omega's mobile-first approach, how to use the many configuration options on the theme settings page, and pitfalls to avoid.
