how would you make something like these old aqua wallpapers? 3d rendering? vector and gradients? i'm curious what the most "period correct" way would be. for that matter, what about the icons? the tutorials on how to make "aqua-like" pill buttons always felt wrong because the shading never quite followed the contour of the shape. how were they done back then, is it all hand-painted or is there a rendering technique i don't know about?
