Is there an alternative to themegarden.org - one that has Drupal 7 themes? I like themegarden.org and I think it'll be a useful tool to help me explain to clients and colleagues how content and presentation can and should be separated. It looks like Theme Garden only caters for Drupal 4.7, 5 and 6. Does anyone know of a D7-compatible site where I can browse themes as easily?
I haven't come across a really good site for Drupal 7 themes. Here are some sites that might be helpful:
