Optic(k)s

I want this book too:
Opticks: Or a Treatise of the Reflections, Refractions, Inflections & Colours of Light-Based on the Fourth Edition London, 1730
by Sir Isaac Newton

The ideas of lenses, telescopes and microscopes are bouncing in my head along with the various problems of geometry I have been researching. It is coming through in my artwork as diagrams of the human eye, angles of reflection and dilation of images.

I've also found it just plain fun to play around on bristol with my compass and a black ink pen ;o) These little sketches are becoming reminiscent of Wassily Kandinsky or Paul Klee.
