Some time ago, XKCD made a quip about an internet based matrix of thousands of these digital entities. That quip is now a reality thanks to elite hardware hacker Jeroen Domburg (aka Sprite_TM). In his recent talk called The Tamagochi Singularity at the Hackaday SuperConference he revealed that he had built an infinite network of virtual Tamagochi by implementing the original hardware as a virtual machine. This included developing AI to keep them happy, and developing a protocol to emulate their IR interactions. But he went even further, hacking an original keychain to use wirelessly as a console which can look in on any of the virtual Tamagochi living on his underground network. This full-stack process is unparalleled in just about every facet: complexity, speed of implementation, awesome factor, and will surely spark legions of other Tamagochi Matrices.
