These aren’t good scrollbars, but it’s clear that they were trying to solve certain problems.
And considering Waves were designed to potentially be extremely long, I can understand what they were trying to achieve.
I am ok with design that fails while trying to solve real problems, as opposed to what we have today, where designs fail because they’re trying to either look better or match the current UI fad.
