Wow!! This was one of my all-time fave demos, along with Phenomena Enigma and Virtual Worlds. All of them had great music and amazing gfx/coding effects. This was of course, state of the art for its time, and even today, it's still fun to see.
Because of the fixed nature of the A500's hardware, there seemed like lots of competition to obtain the fastest possible frame rates, number of particles or polygons.
And looking back, yeah there are quite a few fractalized things turning up in there!
Congrats on making this demo - nostalgia indeed
The funny thing is that back then "realtime raytracing" was kind of a standing joke
