My high school had murals in the cafeteria, all painted by senior art students. And although my senior year, members of my class did get to repaint one (they went with a Calvin & Hobbes panel), the next newest one was a portrait of John Lennon painted the year before most of my graduating class was born.
This high school, on the other hand, is much more sleek, modern and airy in design than the early-1970s two-storey brick fortress I attended. And the art installation it's getting is much cooler. Swedish artist Kristoffer Zetterstrand, who often references video games and pixel-based worlds in his work, has been commissioned to give this Stockholm school a bit of a trompe l'oeil makeover.
My personal favourite is the barely-there graffiti of the first image, which reminds me of Dare to Dream, a shareware game of the very early 1990s that I remember fondly to this day.
