In the spirit of Festivus some members of our team attempted a Drupal 8 feat of strength to ensure we were able to thoroughly air our grievances about the theme layer in Drupal 8.

Several of our front end developers accepted the challenge to build a simple two-page Drupal 8 theme based off of an older project's design.
