Yes, and I understand, from experience, how difficult a job it is to document
something, well, and keep it updated.

I think that having a few lines of working SDL to demonstrate how something
works is worth pages of documentation and dozens of (often redundant) forum
question and answer threads.

I really liked the following excerpt from Graphics Gems 3:


Since the first volume of Graphics Gems was published, I have spoken to many
and discovered that these books have helped people learn graphics by starting

with the codes
so freely, but I think I now see why this helps. It is often exciting to start
learning a new
medium by simply messing around in it, and understanding how it flows. My piano
encourages new students to begin by spending time playing freely at the
keyboard: keep a
few scales or chord progressions in mind, but otherwise explore the spaces of
harmony, and rhythm. When I started to learn new mediums in art classes, I often
time simply playing with the medium: squishing clay into odd shapes or brushing
paint on
paper in free and unplanned motions. Of course one often moves on to develop

from such uncontrolled and spirited play.
It is difficult for the novice to play at programming. There is little room for
expression or error. A simple program does not communicate with the same range
strength as a masterfully simple line drawing or haunting melody. A programmer
hit a few wrong notes, or tolerate an undesired ripple in a line. If the syntax

because of

things completely right, and everything else almost perfectly. That can be an
realization particularly for the beginner: if a newly constructed program

problem could be in a million places, anywhere from the architecture to data

algorithms, or coding errors. The chance to start with something that already
removes the barrier to exploration: your program already works. If you want to
change it,
