Girih tiles - align curves

Hi all,

I just started a Girih-tiles script (http://en.wikipedia.org/wiki/Girih_tiles) and installed Kangaroo. I was hoping that I could use this to align the tiles with each other. (And use hoopsnake, to pick te next one? I don't know yet...and imagine I'll run into some other problems ;) )

However, I already get stuck aligning the sides. Don't know what went wrong since I basically used the example script?

Does anyone have a clue?
