threw together this simple drawing tool that
let me play with line weight in real time while i traced. wanted
to see if this would make anything satisfying vs. my work yesterday.
after i made a drawing i saved it out as postscript,
by "printing" to a postscript printer driver - then selecting
"save as file - postscript".
this allows me to open the image as scalable vectors
in illustrator and manipulate them further.
