The secret smiley inside a microchip

Engineer Kenton Smith's discovery of a microscopic smiley face on a 2020 chip led him to the world of 'silicon doodles'. These hidden images, dating back to the 1970s, were expressions and anti-theft measures by chip designers. Collectors like Smith and CPU_Duke now hunt for these relics, driven by a passion to archive them before they are lost to scrap.
