The Tamagotchi craze started during the 1990s, with the original electronic toys. Years before our smartphone obsession, Tamagotchis were pixelated pets you carried around, often on a keychain. You had tiny rubber buttons and a miniature screen to feed, clean, and take care of your Tamagotchi. If you failed, you returned to a tiny digital tombstone.

In recent years, Tamagotchis have made an unlikely comeback. But now, a team of students at Northeastern University want to build something much more real.

SquidKid looks like a whimsical cartoon squid, but it’s actually a “bioreactor,” essentially a biological life support system. Inside it, floating in a special “broth”, are millions of real, living, glowing bacteria. The students who designed it are blunt.
