Pixel Skylines is a running collection of urban background art pulled from old video games — the parallax cityscapes and coastlines that scrolled behind the action while you were busy paying attention to something else. Isolated and stilled, they turn out to be small, deliberate pieces of landscape painting: a Rio-style skyline with its mountain and statue rendered in a few hundred careful pixels is a good example of what’s in the archive. Worth a scroll if you like seeing background art get promoted to foreground.
