Themes allow you to change the look and feel of your Drupal site. You can use themes contributed by others or create your own to share with the community. Contributed themes are not part of any official release and may not have optimized code/functionality for your purposes.
You can also create a sub-theme of an existing theme. A sub-theme inherits a parent theme's resources. Read more about Sub-theme structure and inheritance.
You can also view a full index of themes listing only their titles.
This fixed blog style layout can work with 1 or 2 sidebars. Features include and/or are inspired by some of my favorites from themes like basic, genesis, and zen. Users will likely enjoy the easy editing sidebars (hover menu), footer links area (for extra links), tableless, xhtml, css, validates w3c, and nifty icons (GPL) from Lullabot... and it is based on the 960 grid system.

OpenG (Open Grid) is a Drupal base or starter theme that serves as Lego for your creativity. The grid based theme, loads content first and allows designers to easily configure a layout based on either a fixed 960px or liquid grid divided into 12, 16 or 24 columns. Easily manipulate the layout via the browser to match the design and configure the grid through the theme settings page without touching code.

Midnight is a new theme that is mainly geared towards blogging. It has a user information bubble available for nodes and comments where information displayed is dependent on permissions like access profiles, access comments, display post information, etc. It comes with the option for two sidebars or just one. Both are displayed to the right of the content. It provides a default user picture unless something else is provided. The navigation is a region. There is also a region within the node, and a region below the content above the footer for whatever you can think to put there.
