Technology today is all about Windows 8, Mountain Lion, tablets and retina displays. So it's always fun to see someone paying tribute to the technology of old for no good reason. In this case, it's a brave soul who installed a 16-year-old verson of Mac OS on a Nook Simple Touch ereader, answering the question nobody asked: What would Mac OS have been like with a touchscreen?
The ereader is running a version of Mini vMac that had been ported to Android and was then hacked onto the device by members of the 68k Macintosh Liberation Army forums. According to member FlyingToaster, both System 7 and 7.5 run on the device, though 7 is less crash-prone. Also, the e-ink screen suffers from a fair amount of ghosting, which should shock nobody. But yes, you can revisit staples such as the Flying Toasters screensavers, games such as Super Munchers, and the ability to design your own desktop background in the system settings (the best part!). To top it off, FlyingToster posted a full gallery here.
The Nook is more than powerful enough to emulate Mac OS, but from the sounds of things (and as common sense would dictate), this whole endeavour is more novelty than anything else; the device isn't really designed for a mouse/keyboard (though there is a hack for keyboards) and Mac OS obviously wasn't made with touch functionality in mind.
