Artist Joshua Allen creates innovative ‘Inflatable Bag Monsters’ by using the air flow generated from subways streaming through the underground tunnels of good ol’ NYC. What do I mean by this? Well, Josh can create the Lockness monster out of recyclable trash bags and some wind. Oh yea, and he made a polar bear and a giraffe. Talk about cute environmentally-friendly art that makes every kind of pedestrian smile. Thanks to this video, you can also be a couch potato (computer potato?) and smile. Go ahead, smile.
