I discovered some references to Wabi Sabi recently. The term seems to convey things that I am interested in expresssing in my work.
Wabi-sabi represents a comprehensive Japanese world view or aesthetic centered on the acceptance of transience and imperfection. The aesthetic is sometimes described as one of beauty that is “imperfect, impermanent, and incomplete”. Read about it here.
Characteristics of the wabi-sabi aesthetic include asymmetry, asperity (roughness or irregularity), simplicity, economy, austerity, modesty, intimacy and appreciation of the ingenuous integrity of natural objects and processes.
