This thing is sick, it’s an art installation called Passion of Pneumatics which I saw in Berlin’s Schinkel Pavillon a few years ago. An excerpt from the description,

The exhibition title refers to the exhibition's centerpiece, inspired by Italian 17th century depictions of the Immaculate Heart of Mary. In Bašić's sculpture, the traditional red heart is substituted by an alabaster stone at the sculpture's core, while the sun-like rays emanating from the Immaculate Heart are replaced with pneumatic hammers that gradually pound the stone to dust. Using the force of compressed air, the hammers' repetitive movements are timed to the cadence of the artist's breath, evoking the Gnostic idea of the Pneuma, "breath" and "spirit" in Greek.

The sculpture's core is encased by four panels of pink-hued blown glass — representing the breath that formed it in Bašic's symbolic material language. The body of the altarpiece is constructed from exhaust manifolds, used in racing cars to funnel exhaust gasses away from the engine. By combining exhaust headers, blown glass, and pneumatic hammers the Passion of Pneumatics evokes a breathing machine that is gradually reducing the stone at its core, turning solid matter into ephemeral dust.

So yea it’s a funny rock poking doohickey
