Because the ideas
come
so
fast in
the area of
graphics,
we
have
deliberately
chosen
to
show
you
a lot of
examples without
getting bogged
down
in detailed
explanations of
how
each
one works. There
is
no
substitute for
lots
of experimenting with
graphics,
and you
now
know
the
basics.
Put
in
your
time,
stuci
,
he examples, and soon you
can apply
for
member-
ship
in
the
artists'
guild.
