( CNN ) -- Half the fun of Halloween is coming up with new , creative outfits that will blow your friends ' minds and maybe scare a few impressionable children . ( The other half , obviously , is candy . ) Technology can help . Take , for example , that classic Halloween accessory , the realistic festering wound . Former NASA employee Mark Rober has created an app that shows animations of moving , oozing innards . Put your iOS or Android smartphone in a special fleshy case , add a carefully bloodied , ripped T-shirt and you have the iWound . There is also a moving eyeball outfit , and a new effect that makes it look like a hand is ripping out your guts from behind . Rober first got the idea for mixing Halloween and smartphones in 2011 . Using two iPads and the FaceTime video chatting app , he strapped one tablet to his front and the other to the back . The live video feed made it look like there was a hole blasted through the center of his body . One hit YouTube video later , and Rober had found his new calling . This year , he quit his job as a mechanical engineer at NASA and started Digital Dudz , a company that makes costumes that integrate tablets and smartphones . You do n't need to be an engineer to put together your own high-tech costume though . Portable battery packs , LED lights and cheap motors can all be used to make ingenious costumes . Check out some of the brilliant ideas on Instructables , in Make Magazine or on YouTube , where people like to show off their creations . There are also the tech-themed costumes . All you need to be a giant iPhone is some cardboard , paint and patience . If you 're going for a minimalist vibe , you can always dress up like a tech company executive -- just add a black shirt or hoodie .
