WordPress.com have announced a new theme called Fusion. The theme is said to be great for a variety of uses including technical blogs, long-form writing, posting code samples, and displaying large images.
Fusion comes with a widget-ready footer, support for custom header image and custom menu, and options for you to customize the layout. Layout options in Appearance→Themes include fixed or flexible layout, choice of left, right, or two right sidebars, or a full-width main column with no sidebars. You can also choose to display full posts or excerpts only on archive pages.
Fusion can be personalized by adding a custom header image and custom menu and using the various layout options to change the look.
Designed by digitalnature, Fusion is now available for WordPress.com and, for self-hosted WordPress.org sites, from the WordPress.org Themes Directory.
