Hi there, my name is Jordan Ballantine, I'm a filmmaker directing a web series called "The Innovention Show" in it, we take one expert and one object and try to create something new. In our pilot episode which is actually called "The Invention Show" we met up with a sculptor and gave him a "skip bag" He decided to use it as a form instead of those big wooden and metal things he normally uses.
 
If you're interested, below is the video. I hope you enjoy it.
