Dear /r/anime, please help me find a lost post

a while ago, I saw a post that link to a video of Homura from madoka magica dancing to a polka song while firing dual pistols in 3D. It was extremely weird but I enjoyed it. I forgot to like or favorite it and I cant find it anymore. So please if anyone remembers it can they help me. I don't care if this gets downvoted I just want my polka back.
