The Phaleon Giga Demo was probably one of the demos with the longest development process in the Atari ST demo history. It was originally started by The Replicants in 1989, and was supposed to include many demoscreens by their friends of The Union. Unfortunately for various reasons they failed to finish it, and decided to abandon the project in 1990. NeXT decided to give a try, and collected all the assets that had been produced so far. This included logos, demo screens, and a half finished main menu. Considering the state of the project, it was decided to keep only the name, some graphics, and the finished demo screens: Everything else was written from scratch.
