The original IRIS Ultrademo was shown on Enlight '97 outside the compo and in fact was glitchy as hell. In 2012, Dr.Bars decided to rebuild it from the source code available on Open Source ZX, so now it has smaller size and more adequate data loading for every part. If you're still unfamiliar with IRIS, I've gotta tell you that there's a lot of parts here, so be extremely patient while watching this.
