WordPress Themes are files that work together to create the design and functionality of a WordPress site. Each Theme may be different, offering many choices for site owners to instantly change their website look. -- WordPress Codex

For this month we'll have attendees do short (that's the Lightning part) walkthroughs of their favorite themes/frameworks, and then have some Q&A time. There is no projector available at the coffee shop, unfortunately, but perhaps someone can look into securing another meeting space next month (Hawthorne Branch of the Madison Public Library, maybe?).
If you'd like to sign up to do a demo just indicate in the comments which theme you might be showing off; it doesn't matter if it's free, for purchase, or even created by you.
