I know this video has been around since March, and as usual, I’m late to the party, but I have to say it is one of the coolest things I have ever seen:
If you ever wondered what kind of work goes into making Yii 2, then this video is a must see. It’s kind of hard to put into words, but you see the framework evolve as the contributors add to the framework. The music is cool too. Highly highly recommended 3 minutes…
It doesn’t include the most interesting pre-release time. You can actually install https://code.google.com/p/gource/ and check current repo visualization yourself.
wow !! … I didn’t know such video could be done !! … it’s simply amazing !!
ciao
I generated a new version: https://www.youtube.com/watch?v=xAJBvBduqUE
And also Laravel for comparison: https://www.youtube.com/watch?v=rq6eXGo4Gi0
Yii2 for the win 
Can you please tell me the name of song that you have used for the yii2 video ?
Parasail - Silent Partner
It’s an amazing contrast. I don’t think it takes into account Symfony though. It almost gives the false impression that Laravel is a lighter framework, which it is not (as far as I know).
Thanks
