In the early 1980s, crackers began “tagging” software they had broken the copy protection of by embedding graphical screens sending out greetings to fellow members of the piracy community. These so-called “intros” grew in sophistication as rival groups used every ounce of programming prowess to demonstrate to the world their real-time graphics and computer music skills. Within a few years, the scene had developed into a legitimate art form that blends coding wizardry with genuine artistic beauty. We’ll walk through some of my favourite demos and chat a bit about how they were able to obtain such incredible effects with such limited hardware. Not just for graphics nerds, I promise!
