These doodles, also known as silicon art, chip graffiti or chip art, and dozens others like it, are remnants of tech history—from Silicon Valley's infancy to the early 2000s—when innovation was rapid fire and the tech still had a very human touch. Engineers would add the sketches to their microchip designs in the techie equivalent of signing their artwork. They'd etch them on chips that may end up in your cellphone, laptop or calculator. They spent hours crafting them, even though they were frowned upon by those in the C Suite.
