Mark Rober was a Nasa scientist before creating Digital Dudz - a company incorporating mobile phones into costume design. Mark was very successful at NASA and helped with the Mars Rovers, but it was the success when he created an amazing costume for a Halloween party that inspired him to create Digital Dudz. He partnered with Morph Costumes to create some cool costumes using your mobile phone. The cool thing about all of this is that the app is completely free, so you could technically do your own halloween costume incorporating the cool animations...such as your gut being ripped out.
Check out the video of Mark talking about his costumes and look at the costumes on their website: http://www.morphsuits.com/digital-dudz/
