PocketSprite might just hold claim to be the world's smallest portable gaming device.

The tiny, keychain-sized version of the original Game Boy is built to run software from Game Boy, Game Boy Color, Sega Master System, and Game Gear games, but the real beauty of the teeny device is the open-source development platform, allowing anyone with some coding skills to load on whatever you fancy. The PocketSprite is even capable of creating its own Wi-Fi hotspot, to add in new apps with one click. For kit nerds and aspiring hackers, the PocketSprite is available in pre-assembled or assembly required versions.

As The Verge points out, it's a great time for fans of tiny consoles, and other mini-systems are available out there if you know where to look, including PocketStar (which is also crowdfunding on Kickstarter), the Arduino-based 8-bit Arduboy, and the NES-copying BittBoy Mini handheld.

Now, catch up on when New York City brand Supreme was featured in this 1999 skateboarding video game.
