tutorials and sources

Do you have any tutorials or sources under the GPL that you can share with me to put it onto my german site for beginners? If so, please inform me.

If you want to look at my site to see how empty it is without sources and tutorials cast a glance at: http://www.GLinteractive.de.vu

i have a page with my crap at: http://strony.poland.com/bsekura

it’s not actually tutorials, but the source code is included in the hope it might be useful for someone…
