Found at Wooster Collective: this creative (and non-destructive) street art by a mysterious artist who makes animals out of discarded plastic bags and ties them to subway grates. When the train rushes below, the puff of air makes the animal jump to life!

Looks familiar? Maybe it's because you've seen this post before on Neatorama: Shopping Bag + Subway Grate = Art?

The perpetrators should be found and held responsible for these terrorist actions.
