Okay, this one's not going to be about teaching, it's about doing. Take the HTML example from the Groovy Sass task and rewrite it using Haml. Post a link to your blog or a gist or wherever you like to host code snippets here showing your work.

Then, for bonus points, rewrite that example to use divs instead of a table. If you haven't written table-less tables before, consider this a necessary task. Post a link somewhere for others to see your work and comment.
