A fantastic 2008 campaign by World Wildlife Fund (WWF) has been resurfacing thanks to a recent Reddit post going viral. The campaign, called WWF Japan – Population by pixel, was created by the agency Hakuhodo C&D / Tokyo. Inspired by their work, Imgurian JJSmooth44 made a follow-up to their project as a programming challenge and it’s just as good.

Norwegian Fredrik Carl Mülertz Størmer is mostly famous for being a genius mathematician and astrophysicist who even has a theorem named after him. His accomplishments were so outstanding that he was named a knight in his country by the king of Norway. However, during his college years in 1890, the 19-year-old also enjoyed photography as a hobby and captured some photographs that are considered a historical treasure now.
