Arnold Patrick Martin / Strings and a Dare

Do not — I repeat, do NOT — attempt to play cat's cradle while wearing this ring. This thread and metal piece by Detroit's Arnold Patrick Martin is from his fabulous "tension structure" series, in which he explores geometry and proportion.

Bonus link: this ring also knows a thing or two about tension — it's made of guitar wire! See more, including wires from violins and pianos, at Minnesota's Strings and a Dare.
