Aaron does a sample HTC Zoe for YouTube.  On the HTC One, you can take a combination of traditional pictures and Zoes, which are three second video snippets (which also double up as still images if needed).  From there, HTC Zoe seamlessly brings the video and still images together for a collage that can be shared (as you're seeing here).  The phone does it automatically, so no video editing skills are required.  Better yet, users can choose from several Zoe styles to make the video as unique as possible.
