I'm really impressed with the end results of what I assume as hours of hard work for searching and finding some compatible photos for great transitions of images. I can't say it's a hobby since this is skill at its best. Thanks for sharing this video. People all over the web are going to enjoy this little bit of project.
The background says it took them 6 months, but I can't begin to imagine how much work went into this in those 6 months. As you said, the transition photos would have been a challenge. I'm glad you enjoyed it!
