This is a Drupal port of the popular wordpress theme piano black by mono-lab.
The following block regions are available:
right sidebar, footer area, content, below content
The css already includes some classes for ubercart and can be used for ecommerce sites.
In Drupal 7 the previous searchbox theme layer has moved into a block. In order to show the search field in the header you need to add a search block to the header region (structure => blocks).
