#### Hello ... this is a heavily hacked script by Luuk 
#### instead of printing the result it makes a nice gif
#### when you want to look at the code ... beware of the 
#### ugliest code ever seen .... but it works ...
#### and that's sometimes the only thing you want ... isn't it ...
#### as the original script ... Hope you like it
####
#### Greetz..... Luuk de Boer 1997.
