Spark is a Drupal distribution which aims to be "the Pressflow of Drupal authoring experience." The goal of Spark is to act as an incubator for Drupal 8 core authoring experience improvements that can be tested in the field on real sites with real users and real content as a Drupal 7 distribution.
You can view a list of features on our Spark project page or http://www.sparkdrupal.com/. We welcome participation in the Spark issue queue with testing feedback and especially patches! :)
