If you are not so impressed with the default themes that come with Drupal cms, you can go to Drupal Themes and select the Drupal theme that does impress you.

Select Drupal Theme

There are several hundred different themes available so you can limit the number of displayed themes by using the "filter by compatibility" block located on the themes page.

If you are a website builder, and use a Content Management System (CMS) for your webpages, you will love the Bitnami Stack. The Bitnami Stack has made huge advances since the beta version I used a few years ago. Not only is it easy to download and install, but it comes preconfigured with Apache, Php5 and MYSQL5 or postgre SQL. It runs quickly and smoothly right out of the box. It supports Linux, Windows, and Mac installations.
