Proyecto is a free WordPress theme that I created for those who want to setup a business and/or portfolio website.

The theme includes a custom homepage with an image slider, highlights and latest portfolio items. All you need to do is add your content and everything is setup automatically. The portfolio is created with a custom post type (portfolio) so you can add your items just like regular posts. You can have unlimited portfolio items and categories. Plus, there is a portfolio page template with a simple jQuery filter for sorting the items.

Besides the cool business/portfolio features, Proyecto also has a full blog section which you can use together with your site or if you choose, you can make the blog page the homepage and simply run a blog using the theme.
