Last year NASA engineer Mark Rober put together a high-tech costume using two iPads to create the effect that he had a hole completely through his stomach. This year, he created a new app spawned from the idea, making it possible for you to do similar things with your smartphone, albeit on a smaller scale.

Given that not every household has two iPads at their disposal for this purpose, Rober created Digitaldudz, a free app for Android and iPhone. The app has preset animations that work with T-shirts, which are available for purchase, or you can design your own costume around the clip.

ABC/Yahoo! News’ “This Could Be Big” recently tested out the gear and spoke with Rober — in a rather interesting way — about the tech. Check it out:

The app includes animations for a beating heart, creepy moving eyes (including ones for presidential candidates Barack Obama and Mitt Romney), and a disco ball for dancers to groove too, among others. Watch this video describing the costumes:
