@mrutkaus,
Ha ha, true, true. That's why I like pictures. Call me dumb, but I can't quite imagine things if there is not a good picture with it. Well maybe I'm exaggerating, but pictures are really important for me, especialy in texts like these. I know, cause every text I read in last 7 years was of technical nature, most of them without pictures, with many (huge) equations.
greets!
