Just to quickly say, scale is problematic as it quickly "blows stuff up"
and controlling it takes a little bit of fiddling. One way of doing this
is to try resetting the transform each time by putting (identity) before
your scales, translates and rotates. This does change how things work as
values will become absolute rather than relative - have a play and
you'll see what I mean.

and I recommend HtDP too!
