No really... I'm not kidding. It's a giant knitted bunny that you can see from space! (zoom in for details)
A group of four Austrian artists called Gelitin spent nearly 5 years knitting the giant rabbit which is located in the Italian Alps. You can find it there for the next 20 years. Seriously. So if you're ever in the area, the artists encourage people to visit. Wonder what fiber they used to knit it because I've seen photos of it in snow, rain, sun... must be acrylic.
