Not as rich as the previous resource suggestion from Dennis :-)

But if you are looking for few minutes break from Skrittering this may be good viewing - this lady is quite good at these videos - in that I am not quite sure whether I like her or not - I am intrigued with her style so it makes me watch more of her videos...

I think they are more for Chinese people learning English - but they seem to be a good bitesize watch for me while I am intrigued...

Just do a youtube search 'OMGmeiyu' and her videos will be there for you to choose from!

Cheers,
Donna
