If you’re anywhere near Yorkshire in England in the next two weeks, you may want to visit the sculpture park of that county’s namesake to see the work of James Capper. An artist-maker who primarily works with hydraulics, I got a glimpse of his machines (above) at the Armory art fair in NYC last month. Blurring the lines between sculpture and engineering, these machines look formidable even when inanimate. They spin, pinch, claw, and force their way through anything in their path. Check out the video below to see his larger earth-walker and earth-churning machines in action.
