I LOVE these! Especially the Millennium one. These websites were soooo aesthetics, my dream at that time was to learn how to create those headers with as many brushes and textures as possible. And yes, they are sooo hard to read (I usually stumble upon similar websites these days and it's even worse now with our bigger computer screens lol), but I gladly compromise my poor eyesight in the name of the aesthetics hehe
90s and 2010s aesthetics were also iconic, but as a zillennial, I'm completely biased towards the 00s one
