The Human Spirograph

Tony Orrico — artist, dancer, human spirograph. He creates remarkable large-scale mock-mathematical drawings with a savant's focus and a marathoner's endurance, sometimes drawing for up to four hours continuously, hitting our soft spot for the intersection of art and mathematics with delicious precision.

See him in action and marvel:

What makes Orrico's art most remarkable is the complete grace and fluidity with which he renders seemingly mechanical drawings, transforming the human body at once into a precision instrument and a delicate paintbrush of the abstract.
