Last year, mattcyborgelt made a name for himself by dressing as the Tinder app, complete with multiple pictures to swipe left and one picture (of himself) that you can only swipe to the right.
But somehow, he managed to outdo himself this year by dressing as the Pokemon Go app.
The costume includes a Pokemon Go stop icon that a person can spin and receive actual plastic Pokeballs from. You can then use those pokeballs to throw at the smartphone screen of the app worn on his body. Hit Pikachu and then ... well watch the video, you have to see it to believe it.
Two years in a row winning costume of the year. Not bad.
