Description

Four pistons and a crankshaft laid out in perfect radial symmetry, ringed by gear teeth, a flower-of-life lattice and geometric arrowheads, rendered in bronze, brass and steel. It works because it treats engine internals the way sacred geometry treats the natural world: as something ordered and worth contemplating. Made for mechanics and gearheads who already think a well-built engine is a kind of art.

Why mechanics grab this one

  • Real engine parts drawn accurately, not decorative gear clip art
  • Intricate enough to reward a close look, bold enough to read across a shop
  • A gift for the wrencher who finds a torn-down engine genuinely beautiful
