Nerds, unite: we’ve found some vintage videogame buried treasure. Control, the “Dutch industry magazine for game developers,” just unearthed some gold: we don’t speak Dutch, but we can’t get over how cool the images are from Control’s recent article on Pac Man creator Toru Iwatani. In the piece, Iwatani reveals his original sketches—yes, that’s right, sketches, with pencil on graph paper—for the Pac Man designs.

Despite their minimalism, Iwatani imbues the designs with a whimsical geometric lyricism. It’s wild to encounter such genius in its primordial-ooze state. What Iwatani create would become one of the most perfect, addictive video games ever; funny to think it all started with a pen and a pad.
