A Squergly Drawing

This is a drawing in my Squergly series. I did a few drawings and a
few paintings, some of which actually got finished. This is one of
the finished ones. I guess I should scan it at a higher resolution.
This was drawn with colored pencils -- probably Berol Prismacolor, I
used to use those alot. I think there's no modification to the
digital image other than maybe a little color modification to get it
to look like the original under normal lighting. A girl I used to
live with and I did some light shows for some friends' band back in
the 80s and used some interference patterns which moved and produced
overlapping clear colors. I was trying to capture the effect of the
color mixing that we got with the projected light.
