Is Gallery website now running Drupal?

I went out to the Gallery website ( http://gallery.menalto.com/ ) to download the latest version and saw the site has a completely new look. What struck me is how "Drupal" like it looked. Then when I moused over some topics, I saw the url is going to /node/xxxx and the forums look like Drupal also. So it appears the Gallery project is now using Drupal for its site. Anyone know for sure, and any information on what it took for them to convert off of whatever they were running over to Drupal? Appears they held onto their content so it would be interesting to hear the effort that went into this.
