Back in the Game Boy-era Nintendo released the Game Boy Camera.
This plastic shooter would go into your Game Boy's cartridge slot and let you take tiny black-and-white photos that were low-res even by '90s standards.
Two decades later someone decided to upgrade a Game Boy Camera by attaching an obscenely large telephoto lens.
And the thing actually works and can take long-distance pictures.
The contraption was made by designer Bastiaan Ekeler, who describes the project in a blog post.
Ekeler used a 3D printer to construct a makeshift lens adapter, attached the adapter to the Game Boy Camera, and then fastened a Canon telephoto lens to the other end.
