If you’ve seen the anime K-On you’ll be familiar with the ending theme of the anime ‘Don’t Say "Lazy"’ by Sakurako Keionbu. Somehow a fan-made live action version has made its way onto nicovideo and subsequently youtube so take a look at this version of the ED yourself. Definitely looks like much effort had been put into the making of the video to make it look as identical to the original. Interesting stuff there.

For comparison, watch the original ED here. I think the live action Yui and Tsumugi characters looked pretty close to the anime version.
