notes: The shrinking of your cow as it rotates is probably due to
a bug in the rotation matrix.  Prof McMillan's slides warn that
the matrix he gives only works if the rotation axis is normalized.
Several people overlooked that and got the same shrinking cow.
You seem to have some problems in your applet when switching between
orthographic and perspective.  When you use orthographic, you need
to scale down the image so that it fits in the same viewport as the
perspective.  And when you switch between the two, remember to start
with a fresh matrix--it looks like you just compose a perspective or
orthographic transformation on top of the already existing viewing
matrix!  Otherwise, good code and nice use of keyboard input to
help test all the cases in your test applet.
