I've been exploring the use of a clear glass orb for a couple of years now. Occasionally it's the subject, sometimes it acts as a lens, and, as on the playground slide image, sometimes there's a complex interplay of multiple levels of reflection and refraction. Aside from the interesting optical effects, it creates an interesting play between what's "inside" the orb and the "outside", which for me is a meditation on the nature of perception and representation. 

Some of these pieces have shown at garner narrative gallery.
