As the poster above me I'd recommend Desert Dream, if nothing then only for the music
And don't forget Enigma by Phenomena, I still love the Mars trip, joyful music. This demo alone made me want to become an asm programmer, and while I was learning it I experimented (in AMOS :-D ) with 3d programming, and since I had no book no nothing, I invented my own strange algorithms that could rotate around two axii.
That was around 1993-94. may those years rest in peace
