Updated homepage

For various reasons I've decided to go back to writing in English.

I'm almost finished with the coding of the art section of my homepage click here to see it
Except for things like background color, margins, size of thumbnails etc (those things will probably be tweaked a little in the future) the only things I want to change now is make the sub-folder thumbnails (the last two) look like they are sub-folders, but still let them show a random pic from the folder, and get everything centered.
I have no idea of how to that though, so the current look will have to do for a while.
