Robert Greenfield posted a timelapse video of him using a shovel to create what he calls the "Snowna Lisa."
The giant drawing is a recreation of Leonardo Da Vinci's famous "Mona Lisa," and his video shows how it's done in less than 40 seconds--however, there's "snow" doubt it took much more time and ton of skill to carve out this massive version of Da Vinci's timeless painting.
Watch the video above to see Robert Greenfield recreate a classic masterpiece in his backyard.
