Len Klikunas was born in 1944 in Chicago, Illinois. Klikunas constructs altered three dimensional canvases and paints them to modify experienced reality through visual perception. The "Blocks" series is a mix of art and architecture, hovering between minimalist painting and sculpture. It employs shizen (自然): the Japanese concept of naturalness, absence of pretense or artificiality.

He explores how to articulate the tension of materials and limits of multi-dimensionality in sculptural paintings. Material is stretched over a supporting three-dimensional framework, like a tent, and coated with paint. Klikunas lines his perforated black artworks with black gauze in order to keep a darkness behind the openings, creating a sense of depth.

The work is characterized by “mindful artlessness” and simplicity and is understated and subtle.
