Righty then,

I think I have a pretty good idea of what to do now, an emalgamtion of most
everything I think!!!!
Tricky business indeed, I think I'll just have a loop within a function to change
the texture each time this way I will only have one version of the model no
matter which way I do it.... funky, no cheree?

Our French class for today is concluded on the note that I know none.
