Part of the video follows a couple of guys who are learning Chinese as they attempt to bargain for goods. The fact that they are learning themselves is a bonus because you can see which bits the native Chinese speakers get straight away and when they struggle to understand. The video also has dialogue from native chinese speaker for key phrases etc.
The real "AHHHAAAA" moment for me though was the section on colours, not too surprisingly the colours are much much easier to learn if you are simultaneously bombarded by objects that match the colour.
I hope if this idea is pursued it will also be released under the Creative Commons licence. As described in my series of posts on podcast remixing this would add a huge new potential in video remixing.
