Middle Name: Danger

Middle Name: Danger is the brother to Baby SweetTooth. It’s got the same magazine-style layout and multiple widgetized sidebars with optional video embed and FeedBurner integration. In fact, everything cool about Baby SweetTooth is there in Middle Name: Danger, the only difference is the boy colors vs. the pink and brown in SweetTooth. Whereas Baby SweetTooth was a re-release, we never released Middle Name: Danger because we were waiting to work out the bugs of SweetTooth. Now that we have, we can release both, side-by-side, as they were meant to be, so you can be set for your baby girl’s blog or your baby boy’s blog (or both!).

photoScape

Second xScape based WordPress theme is photoScape. It has clean and simple block design and is based on only 4 colors. It has 12 default styles built in, each one using only 4 colors and some of them with background images, some without. First idea for usage of the theme is for photography based website and that’s why default thumbnails displayed are larger than it’s usual, making them dominant on the page.

As usual, theme has a BluePrint CSS behind it’s layout and is fully valid with both CSS 2.1 and XHTML 1.0. During the development of this theme, new module for xScape has been made for adding Google Maps into posts, and it’s also now standard element of the framework. To see what else is built in, check out links on the left for theme specific features, and also full framework features.

Ex Libris

Ex Libris was designed for writers and typophiles. Lacking fancy graphical bells and whistles, we focused our attention, instead, on making your content readable with full typographic control. Ex Libris features a unique approach to choosing the typography for your site. Rather than relying on the tired basic web fonts, we’ve embedded the gorgeous free fonts from font foundry exljbris, giving you freedom to style your site with access to full font families and unique typefaces, while maintaining a consistent visual style. We’ve also built the theme with a unique, optional home page layout (Magazine Style, pictured above), and kept an uncluttered approach to page layouts.

If you’re a writer, if you love minimalism, clean design and unique typography, Ex Libris was made for you. Literally.

Erin’s sketchbook

erin’s sketchbook is a minimal WordPress theme we built for ourselves a couple years ago. It’s designed to be a good theme for art or photography, using a black background and minimal design to draw attention to the art or photography. It was based on another theme we did before that, Simple Black which, like Simple Gray, was a minimalist blog theme based around Kubrik. Since the two were closely related, we combined them, offering a theme options page to choose which style you prefer. We also added Twitter @anywhere hovercards, WordPress 3.0 menus, installation notes, and Google’s Droid Sans web font.
