More works using brush pens

Another shape that I explored was to join eight randomly generated points around a local origin, the compositions that would result from generating these these 'zig' shapes were made more unpredictable by using brush pens to plot them.

I was fascinated by the play between the densely filled areas and the untouched spaces. By the way that one seemed to be able to detect the fact tht they were drawn in perspective even though there was also a haphazard quality to the marks. The following detail gives an idea of the qualities that could be found in the shapes that were drawn.

and mapping pens

The next piece is an example of what happened if the registration of the cmy inks worked as intended. The 'hatch' shape was used and only cyan magenta and yellow inks. I was fascinated with the way that the chance alignment of shapes of similar colours leads our attention around the surface, suggesting surfaces and hidden volumes, how the perspective projection of the planes of the 'hatch' shapes create an illusion of an almost tangible physical depth to the coloured shapes intersecting with the surface plane of the paper and the implication that something further might be revealed if we used '3D specs'.


In the next detail we see a piece where a composition like the one above has had a further layer of shapes drawn over the top of it in black ink. as with the images above part of my fascination was with the shapes implied in the areas between the shapes where phantom figures and forms appear to dance in and out of existence as our perceptual systems attempt to make sense of what we are seeing.
