I first saw the work of Magda Cebokli (a Polish-born abstract artist living and working in Melbourne, drawing on her experience in psychology) at an exhibition called Shelf Life at Delmar Gallery, just around the corner from my house. I was pleasantly surprised to see her paintings, and happy to report that Cebokli has been responsible for many other beautiful series of work as showcased on her website. Of these I've been particularly attracted to Ring Cycle from 2011. According to her website:
Circles of shifting light are the focus of this set of paintings which explore luminosity and the structure of space. Continuing on the theme of light and edge, Cebokli now explores it in the tight closed form of series of concentric rings.
In some of the paintings, light on dark conjures up images of a space where light is swallowed inward or pulses out toward the viewer, creating space within space. In others, hard, clearly defined edges become reduced to blur by slight shifts from dark to light.
