Airigami (headed by Larry Moss) made this massive balloon creation currently on display at the Virginia Museum of Natural History. The 20-foot long acrocanthosaurus, a dinosaur from the early cretaceous period, isn't the first huge balloon structure Airigami has made but it is the first to be produced alongside a cast of an actual prehistoric animal. It took four days and ail stand as long as it lasts because, of course, it will die eventually like the dinos did. Below is a video showing the project being constructed.
