Binoculars which can see the wind direction and speed!!! Awesome huh!!

...imagine somebody hands you a device that can quite literally map out the wind activity up to a kilometer out in front of you, showing wind speed, direction and turbulence...

It fires a laser in the atmosphere where it starts to bounce off all sorts of particulate matter floating around in the air. These particles are moving in a particular direction and with a certain velocity that is an excellent approximation of the wind speed at that point - and when they bounce the laser waves back at the device, the doppler effect causes a slight wavelength shift in the returned light. This doppler shift is enough to calculate wind speed and direction at any given point.
