Okay, so even though I've seen this on the news a few dozen times now, I'm still thinking shenanigans are afoot. But still, I couldn't resist pointing you all in the direction of these seriously awesome LED sheep.
So it seems these guys have attached a bunch of LEDs to a bunch of sheep and then performed some serious maneuvers, or "extreme shepherding" as it is called in the video. Then, the video was sped up and we get the appearance of choreographed moving images.
So, if you've ever wanted to see glowing sheep play Pong or burst into an array of fireworks or form the Mona Lisa, you're in for a treat. Just check out the video below. Who knows if it's 100% real or not. All I know, is that it's pretty cool.
