Instant Graphics and Sound, also known as IGS or IG, is a plain-text graphics language created by Larry Mears in 1988 for the Atari ST computer to transmit vector graphics, sound effects, music, and animation from bulletin board systems. It also enabled mouse interactions.
IGS bears many similarities to the later RIPscrip protocol on the PC. Mears began releasing new versions of the IGS software in 2022, after a 30-year hiatus.
