The International Design Culture Conference (IDCC) is an international design conference hosted by Seoul National University. IDCC 2023 was devoted to exploring ideas of speculation, world-building, and alternative realities as design tactics and frameworks. Inspired by symbols that have appeared simultaneously in ancient cave paintings all around the world, Grid designed an omnipresent symbol that can overcome boundaries of time, space, and medium to define IDCC 2023 in any alternate reality.
