While working for Donor Depot, we had the opportunity to work with im2moro in 2010 during their film contest campaign. This was before the big HTML5 migration, so a large part of it was done in flash. The backend used Drupal 6 & the framework theme. The theme used some pretty slick screen detection / fullscreen adaption techniques to keep a consistent, in-scale background and foreground effects on the page.
They have since then updated to a different front-end without flash, but still use Donor Depot's backend CRM and donation features.
