This site is in Spanish (of course you can translate via google or other), but you should check it out just for the pics I mention above...they are about half way down the page on the left hand side and go all the way to the bottom of the page.
Hope someone enjoys them as much as I did...

For anyone interested this website also has some pics of cork oak bonsai in development. Just search suber or subreiro, or look in the blog publications (it is a good blog with articles and the usual bonsai in development...be good if you can speak Spanish?

Cheers, Dario.
