I can think of no creature on this earth more mysterious and otherworldly than the Octopus, with its lack of any bones, three hearts, and 8 seemingly autonomous arms, and a magical grace in the water. I’m not the only one who is a fan of the octopi (one of few creatures with multiple plural forms to go with their other multiple parts) Jens Ohrndorf has put together a simple but interesting model of an octopus seeking a crab lunch. While the use of tires is great at the base of the arms, I am most impressed with the clever use of a space rock to form the large body.
