Kitty Hello:
KRASS!!! :noggin:
Wie hast'n das gemacht!?

Schranz0r:
Gecheatet :)

Aber die Rotationen kann man besser machen Gernot....
Deshalb hab ich alles schonmal in eine Matrix gepackt ;)

Da müsstes du mir evtl. helfen?!

Moru:
Please don't make this into an german only programming language, it's so nice compared to others it's sad that much of the information on the official forum already is in german. Don't close out the rest of the world!
