Hey - Ryumaru - don't take this the wrong way dude - but It makes me laff the way you describe the demoscene with the word 'basically' in that it wasn't that in the slightest - in fact - it was a great deal of hard work... but I know what you mean - you're absolutely correct though... and yes it does go beyond the amiga... the c-64 was a big demoscener machine... it may go back beyond that too - but that's out of the limits of my knowledge...
sorry, no disrespect to the scene! i only know what ive gathered from looking and observing plentifules of sites. im not even as old as the scene itself.
