Remember back in the day when you were a kid and tree houses were all the rage? Well Horace Burgess of Tennessee might have built the ultimate, and world’s largest tree house - 11 floors, somewhere between 8,000 - 10,000 square feet and a miniature basketball court to boot! Check it out here.

Speaking of world’s largest, a giant version of Lenoardo da Vinci’s Mona Lisa (the original is housed in the Louvre in Paris) has gone on display at a shopping center in Wrexham, UK. Spanning 17.5m across, its about 50 times the size of the original work of art.
