Here is an example of a presentation I wrote and performed for a case review in our Law & Ethics class... the auditorium was the entire 2nd year students (our classmates) and was restricted to 2 minutes (preferably less).  My group members were exceptionally hardworking and summarized the case's key points and rubric qualifiers for the project.  Over the weekend, I brainstormed, wrote the lyrics, performed the rap, and edited the audio file that was used to create the presentation with a working poster.  I was fortunate to have such an ambitious, fun-loving, and brave team, who indulged my vision for the presentation.  We received rave reviews, class notoriety, and an A+ for our efforts.
