{\bf Simple exercises } \par

\begin{itemize}
\item Get a bitmap from somewhere and print it out.  Use any bitmap you can
find; if you can't find any, there are at least three available as {\it
/mit/postscript/*.bitmap} [These are each 32 x 32 bit images].
\item Fill in a spiral:  Divide the spiral into appropriate divisions and
shade them to taste.
\end{itemize}

{\bf Slightly harder}
\begin{itemize}
\item Look at the items ({\em keys}) in a font dictionary and print them
out.
\item Define a font in which one character in the font is a spiral.
\item Write a string in which you fill the characters with smaller version
of the character itself (e.g. if you draw an {\it A}, it is filled with or
built out of smaller {\it A}'s). 
\end{itemize}

{\bf Still harder $\ldots$}
\begin{itemize}
\item Redefine a standard font to have an accented {\it e \/}. (.e.g. \'e)
\item Write text in a spiral.  Perhaps have the text diminish and/or fade
as it nears the center.
\item Write a string that darkens from left to right (yes, the darkness
should change within each character).
\end{itemize}
