We’ve added a few nice WordPress template sets recently.
Autofocus and Mansion are photo-blogger themes that display a nice grid of your most recent images. Shaken Grid is also for a photo-specific blog, but shows some of your text as well.
Two new black-background themes are Silent Film and Black-LetterHead. Silent Film has a cute old-timely quality, while Black-LetterHead is a minimalist two-column layout.
