That is really neat, never knew it existed. Thanks for sharing! This site is great.
Markwart, you are new here and already really making some really great contributions. I for one really appreciate it!
Also: I'd like to help with the English, as your signature requests:
"I am intersting in the dimensions" should be "I am interested in the dimensions"
I'll help whenever I can, maybe you can help with my terrible German!
