Technically, it doesn't seem to be pushing boundaries. Just takes advantage of A500's strengths: it's mostly playfields and blitter polygons. But has more coherent style and "story" than usual demos.
Polygon (like that tessellated woman) animation playback was pretty smooth. Although I'm guessing the data includes just the differences between frames, and not redrawing everything.
But yeah, no major boundary pushing going on.
Regardless, this is now my new #1 Amiga demo ever.
Yeah, the style and coherency of all the effects give an amazing result. The rest of this year's contributions were quite good, but this was something else.
