Eigentlich sollte hier der Sourcecode für das Bild rechts stehen, aber durch einen HD-Crash ist der verloren. Aber ich habe eine ältere Version wiedergefunden - muß mal schauen, ob ich das bei Gelegenheit wieder zurechtbasteln kann.
The following code does NOT belong to the image at the right. It's an older version, and erroneous. Due to an HD crash the original source is lost. I'll try to rebuild it, but in the meantime the code below may be useful for someone.
