Thanks for pointer to the following site is due to 
Emily Ju-Hwa Huang.  There are lecture notes, demo code,
source code, experimental applets on graphics.  The
ones I sampled were nicely done.  You may wish to look
at this during the course.

Also, some of the following sites were used during Class
on 9/14/04.  I found all these sites by doing

google: affine transformation graphics

 www.cs.virginia.edu/~gfx/Courses/ 2004/Intro.Spring.04/Lectures/lecture05.ppt
(used for much of the class presentation) (I could not get to this
site by directly using the above url, but could access the returns
from my google search.)

(better explanation of shear)

 PDF only

 http://cyl.cs.cf.ac.uk/teaching/graphics/CG-6.pdf (text mostly)

 http://www.cs.hku.hk/~c0271/notes/c0271-notes-04.pdf (some nice images)

 http://www.mpi-sb.mpg.de/units/ag4/teaching/uebung/lecture02.pdf (H. P.
Seidel, good back-up) (good example of non-commutativity of transformations)
