viel Spaß!

Edit: Die Schrift beginnt jetzt außerhalb des Fensters
Mit dem Alphakanal der OffColor kann man übrigens das Nachglühen einstellen 0x66111122
Die OnColor muß den Alphawert 0xFF haben!
Es gibt noch ein paar Bugs, wenn man die Größe des Fensters oder der Leds verändert
das werd ich mir mal ansehen, wenn ich etwas mehr Zeit hab 
top super sache und das mit nicht eimal 100 zeilen code
