Your house keys? Yeah, they run Doom.
Hardware modder Sprite_TM has put together this custom bit of hardware, a homemade Game Boy clone designed to fit on a keychain, based around a one-inch 96×64 OLED screen and a ESP32 chip with the primary purpose of, well, playing emulated Game Boy games. It also has a few other tricks up its sleeve, in the form of a rough source port of Doom and a VNC forwarding client for streaming Real Big Kid Games from your computer.
