Hi Nicolas, the site looks really nice - I like the colors of the latest iteration.

In Firefox on Windows though the buttons seem to be misbehaving - http://i.imgur.com/4FVwZ03.png.

And I think the buttons in the dark iteration look nicer than the light iteration - they're more uniform, and having the text underneath them looks a little better, IMO - http://i.imgur.com/5ninomb.png.

Just my thoughts - I really like it so far :)
