Continent

Unique layout Theme call Continent WordPress Theme.

Simple Gray

Simple Gray is a minimalist WordPress theme we did a couple years ago. Having not touched it once in over a year, with the launch of Museum Themes, we figured it was time to revisit it. We’ll be revamping all our old free themes and officially releasing some of the ones we never got around to. Added features to Simple Gray are Twitter @anywhere hovercards, WordPress 3.0 menus, installation notes, Google’s Droid Sans web font, and some nice css3 shadows for browsers that can see them.

Thematic is a free, open-source, highly extensible, search-engine optimized WordPress Theme Framework featuring 13 widget-ready areas, grid-based layout samples, styling for popular plugins, and a whole community behind it.

Hybrid Core

Hybrid Core is a WordPress theme development framework for creating solid parent themes. It allows theme developers to forget about all the complex functionality and dive straight into coding their theme’s HTML, CSS, and JavaScript.

This framework’s code is completely free and open source. You can use it for creating publicly-downloadable themes, client work, or even a commercial theme business.

Color Garden

Color Garden is a free theme released on Museum Themes under the GPLv3. This theme is jam-packed with features, from WordPress 3.0 functionality to Twitter integration. Color Garden uses WP3.0′s custom header option, and comes with 4 unique headers that accent the 4 color palette options available on the theme options page. We’ve also built in custom menus, custom backgrounds, and post thumbnails, hitting all the bases for cutting-edge WordPress functionality. If you use Twitter, we’ve got you covered there, too, integrating Twitter’s new Tweet button into our existing social sharing block on single post pages and providing options to display your latest tweets in the sidebar or the footer. The footer and sidebar are completely widgetized, and the footer has three distinct columns to add widgets. If that wasn’t enough, we’ve embedded a custom typeface in the header using CSS font-face. Each color palette has its own unique stylesheet, so you can easily use this theme as a framework or build child themes (or skins) for it.

Carrington Build

Creating custom WordPress page layouts with Carrington Build is as simple as drag-and-drop. By adding content Modules and WordPress sidebars and widgets you’re free to create any page layout you can possible imagine.

ChildThemes for ClassiPress

ChildThemes for ClassiPress, the most popular and widely used classified ads software for WordPress.

Elemental

A commercial theme by ProThemeDesign that is as useful as a framework as it is normal. It comes packed with options for customizable layouts, typography, navigation, widgets, page templates and more, all giving it the power to make any type of WordPress site.

Baby SweetTooth

Baby SweetTooth is a magazine-style theme styled for your baby girl. It takes inspiration from premium WordPress themes, scrapbooking, and baby girl’s clothing and decor. It’s built to share all of your thoughts and memories, pictures and videos in an easy-to-access page. If you use FeedBurner, you can add your FeedBurner ID in the theme options page and have your visitors, friends and family subscribe to updates by email. The theme options page allows you to specify which categories display on the home page, what images to use, everything that requires setting up, and the theme is smart enough to know if you haven’t set up some crucial areas, it won’t display them. Rather than forcing you to edit code just to get your site set up (which, if you’re doing a baby blog, you probably have much better things to do), we put all those variables in the back-end with easy documentation and a welcome page that lets you know when you need to set up your theme options.

In short, we took all the power and functionality of a premium theme and combined that with the appeal and design of a simple mommyblog. And made it free.
