Brain on… was sculpted with hollow steel squares, eliciting both the strength and delicacy of the brain. The squares strip away distractions, leaving a powerful vision and exploration of the human brain, adding an element of mystery and abstraction. Each square represents the trials and tribulations of life; the four corners are the intellectual, emotional, physical and spiritual dimensions of human beings. The surface represents the changes and aging of the brain, still beautiful in all its imperfections.
