Girls, listen up! I am quite sure that you have managed to amass quite a collection of nail polish over the years, and if you are one who always wears a different color each day and love to accessorize your nails, perhaps it is time you checked out what the 22nd century has on offer – the NailDisplay. Sure, the technology that makes the NailDisplay work is not yet in existence, but it has been theorized by a certain Chao-Huai Su and colleagues over at the National Taiwan University in Taipei.

Basically, the rough and clumsy prototype measures a rather chunky 0.5cm thick, sports a 2.5cm diagonal OLED display that is attached it to a large finger ring so that it can be amply demonstrated. The NailDisplay has different uses, where one of them would be to zoom in on the area of the device’s display underneath it, while it also functions as a display for devices without any display such as the iPod shuffle, showing off control buttons and perhaps video playback. Last but not least, the NailDisplay will show content related to the gestures that your fingers make, thanks to a built-in accelerometer. Hey, if it gets thin enough, it could be used to display a different color and pattern each day, now how about that?
