The droplet-inspired Kiyora, while neither practical or impractical (really, who needs to drink purified rainwater?) has some pretty cool upcoming features. Mazda is working on a display system much like the screens in Minority Report:

When the car is off, the IP looks like ice, frozen and hard. When the car is switched on, the display appears to turn into water. Information icons would appear and float downwards to pre-programmed positions in front of the driver. The driver would be able to move the icons around with his finger and could even organise them however he wished. He could lip through menus, select settings for temperature, and even send an email.



However, as cool and eco-friendly as the Kiyora may be, with its 1.3 litre four-cylinder engine, it's not really making an great strides to break away from fossil fuels...
