Just surfing over the code, diving here and there, so I didn't write 
anything in image.
Code in the mail is just the idea (not even syntaxically correct!).
But since you ask, I'm happy to feed the VM tiger.

And don't care too much of my initials, but rather to correct my bugs, 
because i did not and will not test it, i'm just too tired.

Cheers
