I've already wrote this post on "Education" section, but I repost it here for having feedback of C2 developers.
I have made some interactive tutorials (it mean that you see the video and you can interact with it).
I want to know what do you think about them, and if you want more
You can watch them on Youtube :
In French : http://www.youtube.com/playlist?list=PLl25XXpayxo1MCeu9O-W1siUYqHLG0X9Q
In English : http://www.youtube.com/playlist?list=PLl25XXpayxo2NuYtqTqsOE93J10pL0qoC
You can play them on my website :
In French : http://arcade.infokub.fr/tutorials/?lang=fr
In English : http://arcade.infokub.fr/tutorials/?lang=en
And you can download these video for free and legally (Creative Commons)
I hope you will enjoy them !
PS : I'm not really confident about my English translations. So if I made mistakes, please, tell me. Thanks
