I was taking a look at free wordpress themes which are recently featured in Weblog Tools Collection. I did not see many but the following three are really attractive and catch my eyes.
Two columns wordpress theme based on WordPress Admin interface.
Two columns with simple color scheme.
Really looks professional theme. Brightness is a magazine style two columns widget ready theme. You can change the layout in WordPress Admin panel. It uses custom field for featuring posts and displaying thumbnails along with excerpt posts in front page.
