The presentation of Art Gallery O-68 oscillates between ‘concrete constructivism’ and ‘abstracted realism’. Sculptures by Coen Vernooij are not abstractions of a reality, they derive from it. Paintings by Theo Kuijpers are constructivist with colours and shapes in rhythmic patterns. Landscapes by Edgar Knoop show precise control over fortuities of tearing cardboard. Plaster works by Roos van Dijk are geometric in shape, but they spring from reality. The video by Maureen Bachaus ‘Searching for the light’ suggests forms fluttering to fire. Charcoal drawings of nudes by Arlene Diehl leave much concealed, but are not abstract.
