Toshiba Matsushita Display Technology has created a circle-shaped LCD that could be used for digital instruments in cars, according to Fareastgizmos. Why a circle? Because it can fit in certain parts of the dashboard better than cornered shapes, as well as particular design styles. (Think speedometers, tachometers and such.)
Besides, it's a much more dignified fate than resorting to a gimmicky engagement ring box.
