I made a bento video tutorial just now. I just made it for fun and this was my first attempt creating and editing a video (well, more like displaying pictures with background music ;)), so it really doesn't look professional and I still have a lot to learn. But it's fun to make anyway. I hope you enjoy looking at the video as much as I was making it :).
I use Pirates of the Carribbean main theme as the background music, played by the very talented Sungha Jung. Check out his youtube channel, he's got lots of great music improvisations.
