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.

His works explore a dynamic and graceful movement through the use of protruding forms, textured surfaces, and masterful shadow work. The work is characterized by “mindful artlessness” and simplicity and is understated and subtle.
