Have you ever wished you could do something useful with the grass your lawnmower collects in the bag? Apparently someone thought long and hard on that very issue. A few someones, like South Korean students Yong Hee Cho, Yuli Sung, Jee Won Lee and Seung Hee Son. The Muwi mower will take your yard trimmings and compact them into usable shapes like a seat or a grass ball your kids can throw around.

After it figures out the size and shape of your lawn, it will start munching grass by itself and excrete fun shapes. It’s your choice whether you want to clean up the shapes, seat on them or play with them. You might even want to toss them all in your neighbors yard. It’s kind of like having a robotic goat since it munches grass and leaves droppings.
