Halloween will be upon us soon and if your still looking for Halloween costume ideas, then this bizarre “Mad Eye” Halloween costume might be just what you are looking for. Personally I think it may be the best I have seen this year and what’s even more awesome, you can make one for yourself! Designed by Mark Rober, this high-tech looking shirt is simply a modified shirt combined with a free Android/ iOS app. There are a whole bunch of different effects and shirts available from Digital Dudz , but of course the concept lends itself best for a Halloween costume. Be sure to check out the video after the jump to see how it actually works.
