I did this Strange Metamorphosis trailer using prezzi which, as its name suggests, is normally used for presentations.
It turned out to be a great intuitive tool to relate the story. In fact, I’ve left my template public so that anyone can use it to build their own trailer. After setting up my prezi I then filmed it using a screen capture camera. Next, I added the soundscape in a video editing program. The music is simply my old piano. The interactive version (without sound) can be seen right here >>> http://prezi.com/strange-metamorphosis-by-pcr-monk/
