It would be nice if as on your colour quiz, when the results show up the ones you didnt get are filled in with read on the grid. On the other hand, this layout felt better, turkish and tartan next to the germanic languages looked very weird.
not that maltese belongs with germanic but it looks a lot better :) I think I would (ve) do(ne) it as follows: germanic, romance, then either uralic and greek/albanian/irish+maltese, or slavic+turkish/tatar.
basicly paring redwith brown and grey with purple and darkblue.
It is nice to learn new stuff :)
