The demo-scene back in the day was magical. I remember presenting a demo in half ASM half Pascal at The Party in 96 I think it was. Crazy event, 3600 geeks in attendance. We had a gimmick in the demo where it would reset to 80x60 and print a runtime error, only for the music to pick back up and move to the next scene. The entire crowd laughed at that point - But they were evil laughs.
Anyway, a year before we had all reached the level where we could do some very simple 3d with very simple shading/fake lights. That was when Future Crew showed up with 2nd Reality and the double bouncing, transparent balls. I still remember the feeling of amazement and utter loss at seeing that :)
