By designers Sang-hoon Lee and Yong-bum Lim, The "Braun" Bell Mug concept senses liquid levels and chimes at three stages of fullness (about 1/3, halfway and 3/4). It would allow someone without sight to fill a mug perfectly every time while keeping their fingers clear of uncharted waters.
And the best part? There's no element of this design that's too implausible to keep it from manufacture. [Yanko Design via DVICE]
