i’m a fan of the demo scene since 1990… if you are also a fan, don’t miss https://www.pouet.net - the greatest demo archive of the world. no demo is missing there, even not the first demos that ran on the C64 and MSX.
for your real pleasure and if you got a fast PC, i recommend the demos from:
Andromeda, ASD, Alcatraz, Fairlight, Farbrausch, Outracks and don’t miss the top of the month and all time top on pouet.net!
there are still 4kb and 64kb demos - if you saw some of them you’ll wonder what great GFX and musics are possible with only 4kb or 64kb of space, for example Candytron by Farbrausch, Kings Of The Playground by Equinox or Sult by Loonies.
