An owl. A sharky looking bullet. The Hindu deity Ganesh. The Yin and Yang sign. All painstakingly selected and etched onto a microchip that measures about an inch square. Each microscopic silicon doodle was the handiwork of engineers at Qualcomm Incorporated, a San Diego-based company that creates wireless technology-related products and services. The engineers slipped the drawings into Qualcomm's Q1650 data decoder with care not to disturb any of the chip's functions. They were purposeless etchings, never meant to be uncovered. 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. , Decades ago, designers etched microscopic doodles onto silicon chips to leave their marks. Now, techno-archaeologists search for the tiny fossils., 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.
