Sodele.

Ich habe es mal mit gaaaaanz elementarem TikZ gemacht. Ich selber würde es viel einfacher und eleganter lösen, aber so ist es auch für einen Anfänger leicht nachzuvollziehen und vielleicht lernt ja der magische Wolf etwas über die "Basics".

[Magic.Wolf]

Danke euch.
Rolli's Entwurf war zu groß deswegen habe die die Lösungen kombiniert.
